The asymmetric unit of the title complex, {[Cd2(C10H10N3O3S)2(C10H8N2)(NO3)2]·4C3H7NO}n, consists of one CdIIcation, oneN-[2-(2-hydroxybenzoyl)carbamothioyl]acetamidate ligand, half a 4,4′-bipyridyl ligand, one coordinating nitrate anion and two dimethylformamide solvent molecules of crystallization. The bipyridine ligand is completed by inversion symmetry. The metal cation exhibits a distorted pentagonal–bipyramidal coordination geometry provided by two O and one N atoms of the thiosemicarbazide ligand, two O atoms of the nitrate anion, one S atom of a neighbouring thiosemicarbazide ligand and one 4,4′-bipyridine N atom. The bridging role of the thiosemicarbazide ligand through the S atom leads to centrosymmetric binuclear units, which are further linked by 4,4′-bipyridine units, forming polymeric chains extending along theb-axis direction. An intramolecular N—H...O hydrogen bond occurs. The crystal structure also features N—H...O and O—H...O hydrogen bonds, leading to the formation of a three-dimensional network.

In the title complex, [Ag(NO3)(C5H5NO)]n, the AgIatom is coordinated by two O atoms from two different 4-pyridone ligands and two O atoms from one nitrate anion, displaying a nearly planar coordination geometry. The O atoms of two 4-pyridone ligands bridge two symmetrically related AgNO3units, forming a dimer, with an Ag...Ag separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak Ag...O interactions [2.765 (2) Å], Ag...Ag interactions [3.1511 (4) Å] and π–π stacking interactions [centroid–centroid distance = 3.623 (4) Å]. N—H...O and C—H...O hydrogen bonds assemble these chains into a three-dimensional network.

Centrosymmetric Dimers

The reaction between 4,5,6,7-tetrahydro-2-(4,5,6,7-tetrahydro-1,3-benzodithiol-2-ylidene)-1,3-benzodithiole (common name: 4,4′,5,5′,6,6′,7,7′-octahydrodibenzotetrathiafulvalene, OMTTF) and an excess of iodine in tetrahydrofuran (THF) yielded the respective radical organic polyiodide salt, C14H16S4 +·I3 −. The asymmetric unit contains one and a half formula unit of both the cation and the anion, with the half-ions completed through inversion symmetry. The (OMTTF^\bullet+) positive charge can be assigned by the bond distances and the planar structure of the C2S2C=CS2C2 central fragment. In the crystal, trimers of triiodide anions are connected through secondary intermolecular I...I interactions into almost linear I9 3− polyanions. The non-centrosymmetric OMTTF radical cations are linked by S...S interactions into centrosymmetric dimers, while the centrosymmetric OMTTF cations remain as discrete units. The (OMTTF^\bullet+) radical cations and the triiodide anions are linked by weak C—H...I and C—H...S interactions into a three-dimensional network. This work reports the fourth crystalline modification of the C14H16S4^\bullet+·I3 − salt. The three previous modifications were obtained from a mixture of acetonitrile and toluene [Konarev et al. (2005). Synth. Met. 151, 231–238].

The title complex, [Rh(C10H15)Cl(C14H12N2O4)]Cl·2C4H5NO3, has been synthesized by a substitution reaction of the precursor [bis(2,5-dioxopyrrolidin-1-yl) 2,2′-bipyridine-4,4′-dicarboxylate]chlorido(pentamethylcyclopentadienyl)rhodium(III) chloride with NaOCH3. The RhIIIcation is located in an RhC5N2Cl eight-coordinated environment. In the crystal, 1-hydroxypyrrolidine-2,5-dione (NHS) solvent molecules form strong hydrogen bonds with the Cl−counter-anions in the lattice and weak hydrogen bonds with the pentamethylcyclopentadienyl (Cp*) ligands. Hydrogen bonding between the Cp* ligands, the NHS solvent molecules and the Cl−counter-anions form links in a V-shaped chain of RhIIIcomplex cations along thecaxis. Weak hydrogen bonds between the dimethyl 2,2′-bipyridine-4,4′-dicarboxylate ligands and the Cl−counter-anions connect the components into a supramolecular three-dimensional network. The synthetic route to the dimethyl 2,2′-bipyridine-4,4′-dicarboxylate-containing rhodium complex from the [bis(2,5-dioxopyrrolidin-1-yl) 2,2′-bipyridine-4,4′-dicarboxylate]rhodium(III) precursor may be applied to link Rh catalysts to the surface of electrodes.

Each metal ion exhibits a distorted tetrahedral coordination geometry consisting of two pyridyl and two benzimidazole N atoms from four distinct ligands. Two metal ions are linked by two bep ligands to form a centrosymmetric 18-memberedM2(bep)2metallacycle, while adjacentM2(bep)2metallacycles are further interlinked by another two bep ligands resulting in a ladder-like array. In the extended structure, four adjacent ladder-like arrays are connected together through C—H...F, O—H...O and C—H...O hydrogen bonds between bep ligands, solvent molecules and counter-anions into a three-dimensional supramolecular structure.

Molecules in the title compound, [Cu(C12H13N2O3)2], are linked via weak C—H...O and C—H...π(arene) interactions into a three-dimensional network. The Cu atom lies on an inversion centre, and therefore the asymmetric unit contains half a formula unit. The coordination geometry about the Cu atom can be described as tetragonally distorted octahedral.

The Ni atom in the title complex, [Ni(C2H3O2)2(C15H13N5)] or [Ni(CH3COO)2(tpdaH2)] (tpdaH2 is tripyridyldiamine), has a distorted octahedral coordination geometry formed by the tridentate tpdaH2 ligand and two acetate groups. The tpdaH2 ligand is mer-coordinated, with the N atom of the central pyridine ring in the equatorial position and the N atoms of the peripheral pyridine rings in the axial positions. The remaining three equatorial positions are occupied by the O atoms of two acetate anions. The H atoms of both NH groups of the tpdaH2 ligand are involved in strong hydrogen bonds with O atoms of adjacent complex molecules to form a three-dimensional network.

The reaction of bis(3-oxo-1,3-diphenylprop-1-enolato-κ2 O,O′)zinc(II), [Zn(dbm)2], with tris[4-(pyridin-3-yl)phenyl]amine (T3PyA) in tetrahydrofuran (THF) afforded the title crystalline coordination polymer, {[Zn(C15H11O2)2(C33H24N4)]·C4H8O} n . The asymmetric unit contains two independent halves of Zn(dbm)2, one T3PyA and one THF. Each ZnII atom is located on an inversion centre and adopts an elongated octahedral coordination geometry, ligated by four O atoms of two dbm ligands in equatorial positions and by two N atoms of pyridine moieties from two different bridging T3PyA ligands in axial positions. The crystal packing shows a one-dimensional polymer chain in which the two pyridyl groups of the T3PyA ligand bridge two independent Zn atoms of Zn(dbm)2. In the crystal, the coordination polymer chains are linked via C—H...π interactions into a sheet structure parallel to (010). The sheets are cross-linked via further C—H...π interactions into a three-dimensional network. The solvate THF molecule shows disorder over two sets of atomic sites having occupancies of 0.631 (7) and 0.369 (7).
