چکیده

The centrosymmetric title complex, [Cu(2)Br(4)(C(11)H(10)N(2)O(2))(2)]·2H(2)O, was one of three complexes isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 1:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand di-2-pyridylmethane-diol. The copper centers are bridged by bromide donors, leading to a Cu-Cu distance of 4.090 (6) Å. The crystals form as non-merohedral twins with two components related by a 180° rotation around the normal to [100]; the selected sample had a twin ratio of 0.63:0.37.

The asymmetric unit of the title compound, [Hg(2)Br(4)(C(12)H(12)N(2))(2)], contains one half-mol-ecule. The Hg(II) atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric mol-ecule. There is a π-π contact between the pyridine rings [cen...

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 ...

In the title coordination polymer, [CuBr(C(3)H(5)N(3)S)](n), the Cu(I) atom adopts a tetra-hdral CuS(2)Br(2) coordination geometry arising from two S-bonded 4-methyl-1H-1,2,4-triazole-3(4H)-thione ligands and two bromide ions. Both the S and Br atoms act as bridging ligands, connecting pairs of Cu(I) atoms and generating chains propagating in [100]. Inter-chain N-H⋯N hydrogen bonds generate lay...

Each Cu atom in the dinuclear centrosymmetric title complex, [Cu(2)Br(2)(C(14)H(17)N(3))(2)](ClO(4))(2), is ligated in a distorted square-pyramidal geometry (τ = 0.31) by a tridentate bis-[2-(2-pyrid-yl)eth-yl]amine ligand, and by two bridging Br atoms. In addition, the dinuclear species is stabilized by two hydrogen-bonded perchlorate anions.

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).
