Dibromidobis{1-[4-(pyridin-4-yl)phen-yl]ethanone-?N}mercury(II).

ABSTRACT: In the title compound, [HgBr(2)(C(13)H(11)NO)(2)], the Hg(II) atom adopts a four-coordinated HgN(2)Br(2) geometry, formed by two pyridine N atoms from two ligands and two bromide anions. The complex is located on a twofold axis. The coordination geometry is close to forming a see-saw (SS-4) polyhedron, the symmetry-related organic ligands being almost perpendicular; the dihedral angles between the two pyridine rings and between the two benzene rings are 85.5?(4) and 87.7?(4)°, respectively. Within the organic ligand, the pyridine ring is nearly coplanar with the benzene ring [dihedral angle = 13.1?(8)°]. In the crystal, the mol-ecular complexes are connected through weak inter-molecular C-H?Br contacts.

catena-Poly[[chlorido[1-(3-nitro-phen-yl)-2-(triphenyl-phospho-ranyl-idene)ethanone-?C(2)]mercury(II)]-?-chlorido].

Project description:In the title organometallic polymer, [HgCl(2)(C(26)H(20)NO(3)P)](n), the monodentate 1-(3-nitro-phen-yl)-2-(triphenyl-phospho-ran-yl--idene)ethanone ligand is coordinated to the Hg(II) atom through the methine C atom. The Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by one terminal Cl atom, two bridging Cl atoms, and one C atom from the ylidic ligand, resulting in a polymeric chain parallel to [010]. The terminal Cl atom is more strongly bound to the Hg(II) ion [2.3916?(9)?Å] than the bridging Cl atoms. The bridge is asymmetric, as indicated by the two different Hg-Cl(bridging) bond lengths [2.5840?(8) and 2.7876?(8)?Å]. Intra-molecular C-H?O and weak C-H?Cl contacts stabilize the polymeric chain. In the crystal, adjacent chains inter-act via C-H?O hydrogen bonds.

Project description:In the title compound, [Cu(C(7)H(7)N(2)O)Cl(C(7)H(8)N(2)O)]·3H(2)O, the metal ion is five-coordinated by the N atoms from the 1-(pyridin-2-yl)ethanone oximate and 1-(pyridin-2-yl)ethanone oxime ligands and by the chloride anion in a distorted square-pyramidal geometry. The distortion parameter is 0.192. The two organic ligands are linked by an intra-molecular O-H?O hydrogen bond. In the crystal, mol-ecules are linked by O-H?O and O-H?Cl hydrogen bonds. The title compound is the hydrated form of a previously reported structure [Wu & Wu (2008 ?). Acta Cryst. E64, m828]. There are only slight variations in the mol-ecular geometries of the two compounds.

1-[5-Acetyl-4-(4-bromo-phen-yl)-2,6-dimethyl-1,4-dihydro-pyridin-3-yl]ethanone monohydrate.

Project description:The 1,4-dihydro-pyridine ring in the title hydrate, C(17)H(18)BrNO(2)·H(2)O, has a flattened-boat conformation, and the benzene ring is occupies a position orthogonal to this [dihedral angle: 82.19 (16)°]. In the crystal packing, supra-molecular arrays mediated by N-H⋯O(water) and O(water)-H⋯O(carbon-yl) hydrogen bonding are formed in the bc plane. A highly disordered solvent mol-ecule is present within a mol-ecular cavity defined by the organic and water mol-ecules. Its contribution to the electron density was removed from the observed data in the final cycles of refinement and the formula, mol-ecular weight and density are given without taking into account the contribution of the solvent mol-ecule.
