چکیده
The title compound, [Cd2Br4(C24H16N2)2], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two Cd(II) atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the Cd(II) atom. In the crystal, C-H⋯Br hydrogen bonds and π-π contacts between the pyridine and phenyl rings [centroid-centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supra-molecular structure.

In the title compound, [PbBr(2)(C(14)H(12)N(2))](n), the Pb(II) atom lies on a twofold rotation axis. The N-heterocycle-chelated Pb(II) atom exists in a distorted octa-hedral geometry owing to two long Pb⋯Br inter-actions [2.9562 (5) and 3.2594 (5) Å]. These result in a zigzag chain running along the c axis. The lone pair is stereochemically inactive.

The title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(8)N(2))(2)], consists of dimeric units built up around a crystallographic symmetry centre. Each cadmium(II) unit is chelated by a 1,10-phenanthroline (phen) group and two acetate ligands, one of which also acts as a bridge, linking both seven-coordinated cadmium(II) centres. The crystal structure is governed by a single π-π inter-action between...

The title compound, [Zn(NO(3))(2)(C(24)H(16)N(2))(2)], is a twofold axially symmetric coordination compound. Given that the Zn-O interactions [2.4926 (15) and 2.6673 (15) Å] can be considered as weakly bonding and the nitrate ions share the same C(2) axis of the Zn(dpp)(2) fragment (dpp is 4,7-diphenyl-1,10-phenanthroline), these anions belong to the coordination sphere of Zn(2+), leading to a ...

In the mol-ecule of the title compound, [Hg(NCS)(2)(C(26)H(20)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from a chelating 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline ligand and by two S atoms from two thio-cyanate anions. The ligand ring system is not planar. The dihedral angle between the phenyl rings is 53.20 (3)° . In the crystal st...

In the title coordination polymer, [CdBr(2)(C(12)H(12)N(2)O(2))](n), the Cd(II) ion, situated on an inversion centre, is coordinated by four bridging Br atoms and two N atoms from two 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted octa-hedral geometry. The L ligand, which also lies across an inversion centre, bridges two Cd(II) ions, forming layers parallel to (010).
