The title complex, [Sn(C6H5)3(C6H3ClNO2)(H2O)], is five-coordinate with a distorted trigonal–bipyramidal geometry in the solid state. The O atom of the carboxylate group occupies one of the axial sites and the O atom of the water molecule occupies the other. Water H atoms are involved in an intermolecular hydrogen-bonded network with the uncoordinated carboxylate O atom and the pyridine N atom; the interactions lead to two types of rings.

In the title complex, (C18H20N4)[HgI2(C7H3NO4)], the Hg atom exists in a distorted trigonal–bipyramidal geometry formed by two I atoms, one pyridine N and two carboxylate O atoms from a chelating 2,6-pyridinedicarboxylate ligand. Extensive hydrogen bonding between the carboxylate groups and the 1,1′-(butane-1,4-diyl)bis(1H-benzimidazol-3-ium) ion is present in the structure, as well as π–π stacking interactions. The cation has a crystallographic centre of symmetry. In the anion, a crystallographic twofold rotation axis coincides with the Hg–N bond.

Trigonal Bipyramidal

The title complex, [Sb(C6H5)3(C8H4F3O2)2], is located on a twofold axis defined by the metal center and two C atoms of a coordinated phenyl group. The environment of the Sb atom approximates a trigonal-bipyramidal geometry, with the axial positions occupied by the O atoms of symmetry-related 4-(trifluoromethyl)benzoate ligands. In this ligand, the CF3group is disordered by rotation about the C—C bond and the F atoms are distributed over two sets of sites with occupancies of 0.62 (3) and 0.38 (3). In the crystal, molecules are assembled in a three-dimensional framework through weak C—H...O hydrogen bonds.

In the molecule of the title complex, [Sn(CH3)2(C13H10N2O3S)], the Sn atom is in a distorted trigonal–bipyramidal geometry. There are two molecules in the asymmetric unit. A centrosymmetric arrangement leads to an Sn2O2 core through weak Sn...O interactions and causes the formation of a dimer. Intermolecular C—H...O hydrogen bonds seem to be effective in the stabilization of the crystal structure.

AbstractThe title complex, IrCl(bdpp) (1), where bdpp = PhP[(CH2)3PPh2]2, has been obtained from [IrCl(C8H14)2]2 and the triphosphine ligand. Characteristic 31P NMR data of 1 dissolved in THF are δ(P̲Ph2) = 2.7 and δ(P̲Ph) = - 19.9 with cis-2J(P̲IrP̲) = 32.8 Hz. Reaction of 1 with CO proceeds stepwise to yield five-coordinate IrCl(CO)(bdpp) (2) and ionic [Ir(CO)2(bdpp)]Cl (3). A trigonal bipyramidal geometry with equatorial CO ligands is assigned to the cation of 3 on the basis of its v(CO) infrared intensities. When allowed to react with HCl, 1 gives the monohydride IrHCl2(bdpp) (4). Similarly, the dihydride IrH2Cl(bdpp) (5) is formed from 1 and H2. As has been established by IR and NMR spectroscopy, 4 and 5 adopt cis-mer-octahedral structures.

In the dinuclear title compound, [Na2(C13H15ClN5O5S)2(H2O)6] n , two Na+ cations, disposed about a centre of inversion, are linked by two bridging water molecules. The coordination geometry is based on an O5 donor set defined by four water molecules and a 4-aminobenzenesulfonate O atom in a distorted trigonal–bipyramidal geometry. In the crystal, significant O—H...O, O—H...N and N—H...O hydrogen bonds lead to the formation of a three-dimensional architecture.
