In the title complex, [CoCl2(C7H6N2S4)], 2,2′-(methylenedithio)bi-1,3-thiazole acts as a bidentate ligand and chelates one CoII ion through the two N atoms to give an eight-membered symmetric unit. The CoII ion is located on a twofold axis and displays a slightly distorted tetrahedral coordination environment, where the two Cl− anions occupy the remaining coordination sites. The N—Co—N and Cl—Co—Cl planes are nearly perpendicular, with a dihedral angle of 88.0 (3)°.

Distorted Tetrahedral Coordination

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.

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.

In the crystal structure of the title complex, [Cu(C10H9N3)2](ClO4)2, the CuIIcenter is four-coordinated by the nitrogen donors of the pyridine rings of the ligand, bis(2-pyridyl)amine. The crystal structure reveals that the CuN4coordination sphere has a distorted tetrahedral coordination geometry with a crystallographicC2axis through the CuIIcenter. The perchlorate anions link the complex cations to form a chain structure through C—H...O close contacts and N—H...O hydrogen bonds.

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.

In the title complex, [CuBr2(C14H11BrN4O)2], the CuII ion is located on an inversion centre and is coordinated by two ketonic O atoms, two N atoms and two Br atoms, forming a distorted octahedral coordination environment. The two carbonyl groups are trans positioned with C=O bond lengths of 1.256 (5) Å, in agreement with a classical carbonyl bond. The Cu—O bond length is 2.011 (3) Å. The two bromobenzyl rings are approximately parallel to one another, forming a dihedral angle of 70.1 (4)° with the coordination plane.

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each AgIion displays a distorted tetrahedral coordination geometry with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from theN,N′-phenylthiourea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag...Ag separation of 3.2064 (2) Å. In the crystal, complex molecules are linked by N—H...Cl hydrogen bonds forming a dimer. The dimers are linkedviaweak C— H...Cl hydrogen bonds forming a two-dimensional supramolecular architecture in theyzplane. In addition, an intramolecular N—H...Cl hydrogen bond is observed.

AbstractA novel triply bridged dinuclear copper(I) complex: Cu2(μ-paa)(μ-dcpm)2(BF4)2·2CH2Cl2 [ paa = pyridine-2-carbaldehyde azine (C12H10N4) and dcpm = bis(dicyclohexylphosphino)methane(C25H46P2) ] has been synthesized and structurally characterized. Crystallographic studies of the complex showed that two copper(I) ions were bridged by one paa ligand and two dcpm ligands. The paa ligand adopted the Z configuration at the partially double N-N bond and the two copper ions have distorted tetrahedral coordination geometry. Because of the steric effect of dcpm, the pyridine rings of the paa ligand are obviously not on the same plane (the dihedral angle is 43.610). The interaction between neighboring ligands results in a N-N bond length (1.374(7) Å) contraction. The UV-vis spectra of the complex exhibited intense high-energy absorptions at λmax
