The title compound, [Co(CH3COO)2(CH4N2S)2], is isotypic with the corresponding ZnIIcomplex. The metal atom is in a distorted tetrahedral coordination environment with the two S atoms from two thiourea ligands and two O atoms from two acetate anions as the coordinating atoms. All H atoms of the thiourea ligands are involved in N—H...O and N—H...S hydrogen bonds, leading to a three-dimensional network.

In the mononuclear title complex, [CuI(C2H3N)(C26H24N2)], the CuIion has a distorted tetrahedral coordination environment, defined by two N atoms of the chelating 2-(naphthalen-1-yl)-6-[(2,4,6-trimethylphenyl)imino]pyridine ligand, one N atom of an acetonitrile ligand and one iodide ligand. Within the complex, there are weak intramolecular C—H...N hydrogen bonds, while weak intermolecular C—H...I interactions between complex molecules, help to facilitate a three-dimensional network.

In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni2+cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni2+cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni2+cation has an octahedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N—H...Br, O—H...Br and O—H...O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

Crystals of the title compound, [Li{OOP(O-2,6-iPr2C6H3)2}(CH3OH)3]·CH3OH or [Li(C24H34O4P)(CH3OH)3]·CH3OH, have been formed in the reaction between HOOP(O-2,6-iPr2C6H3)2and LiOH in methanol. The title compound is of interest as it represents the first reported crystal structure of the family of lithium phosphate diesters. The {Li(CH3OH)3[O2P(O-iPr2C6H3)2]} unit displays the Li atom in a slightly distorted tetrahedral coordination environment and exhibits one intramolecular O—H...O hydrogen bond between a coordinating methanol molecule and the terminal non-coordinating O atom of the phosphate group. The unit is connected with two non-coordinating methanol molecules through two intermolecular O—H...O hydrogen bonds, and with a neighbouring unit through two other O—H...O interactions. These intermolecular hydrogen bonds lead to the formation of infinite chains along [100]. There are no significant interactions between the chains.

Distorted Tetrahedral Coordination

The title compound, [K2Fe{OCH(CF3)2}4]n, was formed from the reaction of potassium hexafluoroisopropoxide with iron(II) chloride in toluene. The FeIIatom has a highly distorted tetrahedral coordination environment. All four of the non-equivalent hexafluoroisopropoxy O atoms link the FeIIatoms to one of the K+atoms in an alternating chain of Fe—O—K—O fused four-membered rings, with K—Fe distances of 3.715 (2) and 3.717 (2) Å. This K+atom is also bridged to eight of the F atoms. The other K+atom is bonded to only two of the O atoms, but has seven short K...F contacts, one of which links the chains into a three-dimensional arrangement. Weak hydrogen bonding between the lone H atoms on the hexafluoroisopropoxy groups and F atoms is also present. The crystal studied was refined as an inversion twin.

The title compound, [Sn(CH3)3(C6H3F2O2Se)]n, was prepared by treatment of 3,4-difluorobenzeneseleninic acid and trimethyltin chloride with sodium ethoxide in methanol. In the polymeric crystal structure, infinite chains, with the SnIVatom in a trigonal–bipyramidal C3O2coordination environment involving methyl ligands and the bridging 3,4-difluorobenzeneseleninate anion, are present. The chains extend parallel to [010] and are linked through slipped π–π interactions and weak C—H...O hydrogen bonds into a three-dimensional network.

The title complex, [Ag3Br2(C25H22P2)3]Br·C7H8N2S, comprises a trinuclear [Ag3Br2(C25H22P2)3]+unit, a Br−anion and oneN,N′-dimethylthiourea molecule (ptu). Three AgIions are linkedviatwo μ3-bridging Br atoms, leading to a distorted triangular bipyramid with an Ag...Ag separation range of 3.1046 (6)–3.3556 (6) Å. The triangular Ag3arrangement is stabilized by six P atoms from three chelating bis(diphenylphosphanyl)methane (dppm) ligands. The AgIion presents a distorted tetrahedral coordination geometry. In the crystal, the bromide anion is connected to the ptu molecule through N—H...Br hydrogen bonds [graph-set motifR21(6)]. Each bromide/ptu aggregate links the complex ionviaC—H...S and C—H...Br hydrogen bonds, leading to the formation of a three-dimensional network. Two phenyl rings from two dppm ligands were modelled as disordered over two sites.

Distorted Tetrahedral Coordination

The title compound, [Ag2(C6H4N4)(N3)]n, was obtained under hydrothermal conditions at 433 K. The asymmetric unit of the orthorhombic space group (Pna21) consists of two Ag+cations, an anionic 5-(pyridin-4-yl)tetrazolide (4-ptz−) ligand and an anionic azide ligand. Both Ag+centres are coordinated by four N atoms, forming a distorted tetrahedral coordination environment. When all the component ions are viewed as 4-connected nodes, the whole three-dimensional network can be regarded topologically as a new kind of 4,4,4,4-connected net with the Schläfli symbol (4.85)(42.84)(43.83)2.

In the structure of the title salt, (C5H14N3)2[CuCl4], the CuIIatom in the anion lies on a twofold rotation axis. The tetrachloridocuprate(II) anion adopts a flattened tetrahedral coordination environment and interacts electrostatically with the tetramethylguanidinium cation. The crystal packing is additionally consolidated through N—H...Cl and C—H...Cl hydrogen bonds, resulting in a three-dimensional network structure.

Square Planar

The title compound, [NiBr(C25H29N2O)], contains an NiII atom with a slightly distorted square-planar coordination environment defined by one O and two N atoms from the 2-{[(8-aminonaphthalen-1-yl)imino]methyl}-4,6-di-tert-butylphenolate ligand and a bromide anion. The Ni—O and Ni—N bond lengths are slightly longer than those observed in the phenyl backbone counterpart, which can be attributed to the larger steric hindrance of the naphthyl group in the structure of the title compound. The molecule as a whole is substantially distorted, with both the planar naphthalene-1,8-diamine and imino–methyl–phenolate substitutents rotated against the NiN2OBr plane by 38.92 (7) and 37.22 (8)°, respectively, giving the molecule a twisted appearance. N—H...Br hydrogen bonds and N—H...C(π) contacts connect the molecules into dimers, and additional C—H...Br contacts, C—H...π interactions, and an offset stacking interaction between naphthyl units interconnect these dimers into a three-dimensional network.

In the title compound, [Re(C10H6NO2)(CO)3{As(C6H5)3}], the coordination environment of ReIis that of a distorted octahedron. Three coordination sites are occupied by three carbonyl groups in a facial arrangement and the remaining three sites by triphenylarsane and deprotonated quinaldic acid inAs-mono- andN,O-bidentate fashions, respectively. In the crystal, the complexes are linked through weak C—H...O hydrogen bonds, forming a three-dimensional network. It worth noting that, as far as we know, this complex is the first ReItriphenylarsane tricarbonyl compound to be reported.
