In the structure of the title compound, [CdCl2(C4H8N2S)2], the CdIIatom is coordinated by two chloride ions and two 1,3-diazinane-2-thione (Diaz) molecules through their S atoms. The geometry around the CdIIatom is distorted tetrahedral, with bond angles in the range 101.55 (7)–117.91 (8)°. The CH2groups of one Diaz ligand are disordered over two sets of sites with an occupancy ratio of 0.711 (12):0.289 (12). The molecular structure is stabilized by intramolecular N—H...Cl hydrogen-bonding interactions, generating a butterflysynconformation. Intermolecular N—H...Cl and N—H...S interactions lead to the formation of a three-dimensional network structure. The structure has been determined from a crystal twinned by nonmerohedry, by a 180° rotation around the reciprocalcaxis. The twin ratio refined to 0.8866 (6):0.1134 (6).

The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by anO-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuIatoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu...Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic interaction in the actual dimer. C—H...O and C—H...I hydrogen bonding interactions as well as C—H...π(aryl) interactions stabilize the three-dimensional supramolecular network.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

The title compound, [IrCl(C12H8NO)2{(CH3)2SO}]·H3CCN or [IrCl(fppy)2(DMSO)]·H3CCN [where fppy is 4-(pyridin-2-yl)benzaldehyde and DMSO is dimethyl sulfoxide], is a mononuclear iridium(III) complex including two fppy ligands, a sulfur-coordinating DMSO ligand, and one terminal chloride ligand that define a distorted octahedral coordination sphere. The complex crystallizes from 1:1 DMSO–acetonitrile as an acetonitrile solvate. In the crystal, weak C—H...O and C—H...N hydrogen-bonding interactions between adjacent complexes and between the acetonitrile solvent and the complex consolidate the packing.

Anionic Cluster

The structure of a salt of diprotonatedendo-3-aminotropane crystallized with a copper(II) anionic cluster is reported,viz.(C8H18N2)[CuCl3(NO3)(H2O)]. Neither ion in the salt has been structurally characterized previously. In the crystal, the ions pack together to form a three-dimensional structure held together by a network of intermolecular N—H...O, O—H...Cl and N—H...Cl hydrogen-bonding interactions. Selective crystallization of the title compound can be considered as a simple method for the separation of theexoandendoisomers of 3-aminotropane.

Form Part

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron. The two crystallographically independent bdc2−ligands are fully deprotonated and adopt μ3-κO:κO′:κO′′ and μ4-κO:κO′:κO′′:κO′′′ coordination modes, bridging three or four ZnIIcations, respectively, from two Zn4(OH)2units. The Zn4(OH)2fragment connects six neighbouring tetranuclear units through four μ3-bdc2−and two μ4-bdc2−ligands, forming a three-dimensional framework with uninodal 6-connected α-Po topology, in which the tetranuclear Zn4(OH)2units are considered as 6-connected nodes and the bdc2−ligands act as linkers. The uncoordinated water molecules are located on opposite sides of the Zn4(OH)2unit and are connected to it through hydrogen-bonding interactions involving hydroxide and carboxylate groups. The structure is further stabilized by extensive π–π interactions between the pdon and μ4-bdc2−ligands.

In the title compound, [Cd(CH3COO)2(C6H7N3O)2]·2C2H5OH, the CdIIatom, which lies on a twofold rotation axis, is coordinated by two monodentate acetate groups and twoN,N′-chelating pyridine-2-carboxamide oxime ligands, leading to a distorted octahedral coordination sphere. The mononuclear complex molecules are assembled into chains along thec-axis directionviaN—H...O hydrogen-bonding interactions. These chains are further assembled by O—H...O hydrogen bonds involving the ethanol solvent molecules into a three-dimensional supramolecular structure.

The title compound I, C13H10N2O2S2, crystallizes in the monoclinic space group C2/c with eight molecules in the unit cell. Excluding for the ethyl substituent, the molecule of I adopts a nearly coplanar conformation (r.m.s. deviations is 0.058 Å), which is supported by the intramolecular C—H...O hydrogen-bonding interaction between the two ring systems [C...O = 2.859 (3) Å]. In the crystal, the molecules form dimeric associates via two bifurcated C—H...O hydrogen-bonding interactions between an ene hydrogen atom and a carbonyl functional group of an adjacent molecule [C...O = 3.133 (3) Å] and vice versa. The crystal structure is further stabilized by a three-dimensional network of weak hydrogen bonds between one molecule and six adjacent molecules as well as offset π–π stacking. The combination of the quinoxaline 2(1H)-one moiety with the dithiocarbonate moiety extends the aromaticity of the quinoxaline scaffold towards the substituent as well as influencing the π-system of the quinoxaline. The title compound is the direct precursor for a dithiolene ligand mimicking the natural cofactor ligand molybdopterin.

The asymmetric unit of the title compound, [Co(NCS)2(C6H6N2O)4]·2C6H6N2O·C2H5OH, comprises one CoIIcation, two thiocyanate anions, four coordinating and two solvent isonicotinamide molecules and one ethanol solvent molecule. The CoIIcations are octahedrally coordinated by four N-coordinating isonicotinamide ligands and two terminally N-bonded thiocyanate anions. These discrete complexes are linked by intermolecular N—H...O and N—H...S hydrogen-bonding interactions into a three-dimensional network. The two isonicotinamide and the ethanol solvent molecules are embedded in channels of this network and are linked through further N—H...O and N—H...N hydrogen bonds to the network. The ethanol solvent molecule is disordered over two sets of sites (occupancy ratio 0.6:0.4).
