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 title complex, [Cu2(C8Br4O4)2(C6H16N2)2(H2O)2], the CuIIcation is chelated by a tetramethylethane-1,2-diamine ligand and coordinated by a water molecule as well as bridged by two tetrabromophthalate anions in a distorted O3N2trigonal–bipyramidal geometry. The two symmetry-related tetrabromophthalate anions bridge the two CuIIcations, forming a centrosymmetric dinuclear complex in which the Cu...Cu separation is 5.054 (2) Å. Intramolecular classic O—H...O hydrogen bonds and weak C—H...O hydrogen bonds occur in the dinuclear molecule. In the crystal, the molecules are linked by weak C—H...Br and C—H...O interactions into supramolecular chains propagating along theb-axis direction.

The title molecule, [Cu(C12H8N2)2(H2O)](NO3)2, is a new polymorph of a compound which up to now has been reported to crystallize space groups inC2/candCc. The crystal studied was twinned by non-merohedry (final BASF factor of 0.40043) with the structure being solved and refined inP-1. The CuIIatom is coordinated by four N atoms from two 1,10-phenanthroline ligands and an O atom from a water molecule in an approximate trigonal–bipyramidal geometry. Discrete entities of one cation and two nitrate anions are formed by water–nitrate O—H...O hydrogen bonds. The components are further assembled into a three-dimensional network by 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.
