چکیده
The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three 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 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801 (5) Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H⋯O hydrogen bonds are present in the crystal structure.

In the title complex, [Cu(4)Br(CN)(3)(C(10)H(8)N(2))(2)](n), the four independent Cu(I) atoms are all in distorted trigonal-planar geometries. One is formed by one N atom and one C atom from two cyanide groups and one Br atom, one is formed by two N atoms from two cyanide groups and one Br atom, and the other two are formed by two N atoms from a chelating 2,2'-bipyridine (bpy) ligand and one C ...

The crystal structure of the title complex, [Cu(2)Br(3)(OH)(C(11)H(13)Br(0.5)Cl(1.5)N(2)O)(2)], consists of two (2-halo-6-oxazolin-yl)pyridine·CuBr units bridged by a Br atom and a hydroxide group. The Cu(II) atoms are five-coordinate with an (N,N)BrCu(Br)(OH) distorted tetra-gonal-pyramidal core, and relatively short contacts to the bridging atoms (Cu-μ-OH and Cu-μ-Br). There are two symmetry-...

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...
