The Given

The title compound, 2C36H39N3O4·H2O, is a linear π-conjugated ladder oligomer with an alkyl chain on the central nitrogen atom. This diindolocarbazole, prepared via a twofold Cadogan reaction, adopts a sligthly convex shape, anti to the disordered octyl group. The unit cell contains nine molecules of the title compound and half a water molecule per main molecule. The water molecule forms hydrogen bridges, connecting the carbazole-NH and methoxy groups of different molecules. The crystal contains solvent molecules which are located in a channel parallel to the c axis. It was not possible to determine the position and nature of the solvent (a mixure of choroform, n-pentane and DMSO). The SQUEEZE [Spek (2015). Acta Cryst. C71, 9–18] option of PLATON was used to model the missing electron density. The given chemical formula and other crystal data do not take into account these solvent molecules.

Oxygen Atoms

The asymmetric unit of the title compound, [Co(C12H8N2)2(H2O)2]2[Ge(C6H5O7)2](NO3)2, features two complex [(C12H8N2)2(H2O)2Co]2+ cations, two NO3 − anions as well as one centrosymmetric [(C6H5O7)2Ge]2− anion. Two HCit ligands (Cit = citrate, C6H4O7) each coordinate via three different oxygen atoms (hydroxylate, α-carboxylate, β-carboxylate) to the Ge atom, forming a slightly distorted octahedron. The coordination polyhedron of the Co atom is also octahedral, formed by coordination of four nitrogen atoms from two phenanthroline molecules and two water oxygen atoms. In the crystal, the cations and anions are linked by hydrogen bonds and form layers parallel to the bc plane. The structure exhibits disorder of the NO3 − anion [disorder ratio 0.688 (9) to 0.312 (9)]. There are also highly disordered solvent molecules (presumably water and/or ethanol) in the crystal structure; explicit refinement of these molecules was not possible, and the content of the voids was instead taken into account using reverse Fourier transform methods [SQUEEZE procedure in PLATON; Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s).

The title complex, [Mo(C24H30N2P2)(CO)4], contains a molybdenum centre bearing a P,P′-cis-chelating Ph2PN( i Pr)P(Ph)NH( i Pr) and four carbonyl ligands in a distorted octahedral coordination geometry. This results in a nearly planar four-membered metallacycle. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds to form layers parallel to the ac plane.

One half ZnPc, one ZnTPP and two chloroform molecules define the asymmetric unit, with the zinc(II) cation of ZnPc situated on an inversion centre. In the supramolecule, the central ZnPc moiety is sandwiched between two ZnTPPs moieties in a co-facial conformation with a π-conjugated system, leading to a nearly H-type aggregate with a distance of 3.4967 (5) Å between adjacent zinc sites. The ZnTPP units are slightly glided away to form a partial ecliptic arrangement. Each phenyl group of the TPP ligand is anchored above the N atom of the isoindole linker of the Pc ligand through weak C—H...N hydrogen bonds and is held into the crevice between the two dimethylphenoxy groups of phthalocyanine via van der Waals interactions. In the crystal, chloroform solvent molecules are situated between the supramolecules. There is another solvent-accessible void of 341 (2) Å3. The contribution of disordered solvent molecules situated in this void was removed from the diffraction data using SQUEEZE in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not consider this unknown solvent molecule(s).

In the crystal, the cations are linked with the complex anionsviaweak C—H...F and C—H...π interactions. Two of the four independent thiophene rings are disordered over two sites; occupancies were refined to 0.662 (10):0.338 (10). The solvent water molecules are highly disordered in a solvent-accessible void of 54 (3) Å3; the diffuse electron densities were removed from the data set using SQUEEZE [Spek (2015).Acta Cryst.

The title compound, [Rh(C8H12)(C18H16NP)]BF4has been prepared as a precatalyst for applications in rhodium-catalysed additions of carbocyclic acids to terminal alkynes leading toanti-MarkovnikovZ-enol esters. Here the triclinic pseudopolymorph of the title compound is presented. In contrast to the earlier reported pseudopolymorph (orthorhombic space group) [Weiet al.(2013).Chem. Eur. J.19, 12067–12076], the triclinic polymorph contains half a molecule of dichloromethane as solvent in the asymmetric unit. The rhodium(I) atom exhibits a square-planar coordination. The estimated diffraction contribution of the disordered solvent (a half molecule of dichloroethane per asymmetric unit) was subtracted from the observed diffraction data using the SQUEEZE [Spek (2015).Acta Cryst.C71, 9–16] routine inPLATON. The given chemical formula and other crystal data do not take the solvent into account.

The title compound, a triarylmethanol, C46H64OS12Si3 1, was synthesized via lithiation of tris-2,2,6,6-tetramethylbenzo[1,2-d;4,5-d′]bis[1,3]dithiol-4-yl-methanol, 2, and electrophilic quenching with trimethylsilyl chloride. The current crystal structure reveals information about the reactivity of this compound and compares well with the structure reported for the unsubstituted parent compound 2 [Driesschaert et al. (2012). Eur. J. Org. Chem. 33, 6517–6525]. The title compound 1 forms molecular propellers and crystallizes in P-1, featuring an unusually long Si—Car bond of 1.910 (3) Å. Moreover, the geometry at the central quaternary carbon is rather trigonal-pyramidal than tetrahedral due to vast intramolecular stress. One trimethylsilyl group is disordered over two positions in a 0.504 (4):0.496 (4) ratio and one S atom is disordered over two positions in a 0.509 (7):0.491 (7) ratio. The contribution of disordered diethyl ether solvent molecule(s) was removed using the PLATON SQUEEZE (Spek, 2015) solvent masking procedure. These solvent molecules are not considered in the given chemical formula and other crystal data.

The title complex, [{Os2(CO)4(C21H21P)2}2(C12H14O4)2], is a centrosymmetric molecular loop consisting of two Os—Os sawhorse units linked by two adamantane dicarboxylato bridges. It was synthesized by the microwave-mediated reaction between Os3(CO)12 and adamantane-1,3-dicarboxylic acid. In contrast to the related complex [{Os2(CO)6}2(μ4-adamantane-1,3-diacetate)2], the metal–metal axes within each molecule are oriented parallel rather than perpendicular to one another. The crystal structure exhibits cavities that contain residual electron density peaks, but it was not possible to unambiguously identify the solvent therein. The contribution of the disordered solvent molecules to the scattering was removed using the SQUEEZE (Spek (2015). Acta Cryst. C71, 9–18) routine in PLATON [Spek (2020). Acta Cryst. E76, 1–11].

The asymmetric unit of the title compound, fac-[Ir(C11H8N)2(C18H24N2)]Cl or fac-[Ir(ppy)2(Hppy-NC6)]Cl, contains two [Ir(ppy)2(ppy-NC6)](H+) cations, two Cl− anions and disordered solvent. In each complex molecule, the IrIII ion is coordinated by two C,N-bidentate 2-(pyridin-2-yl)phenyl ligands and one C,N-bidentate N-[4-(pyridin-2-yl)benzyl]hexan-1-aminium ligand, leading to a distorted fac-octahedral coordination environment. In the crystal, the molecules are linked by N—H...Cl, C—H...π and π–π interactions, forming a three-dimensional supramolecular structure. The hexyl group of one molecule is disordered over two orientations with a refined occupancy ratio of 0.412 (13):0.588 (13). The acetone and hexane solvent molecules were found to be highly disordered and their contribution to the scattering was masked using the solvent-masking routine smtbx.mask in OLEX2 [Rees et al.
