Özet

The [Cu(C6H2Br2ClO)(2)(NH3)(2)] complex was synthesized and characterized by XRD, UV/vis, FTIR, DSC, elemental analysis and magnetic susceptibility measurements. The structural analysis of the title complex indicated that it is a monomeric centrosymmetric compound which crystallizes in the monoclinic system, P2(1)/c, and has a trans-planar CuO2N2 coordination [Cu-O 1.940(5) and Cu-N 1.978(7) angstrom]. In the coordination sphere of the Cu atom, there are long range interactions with Br2 and the centrosymetrically related Br2i (i: -x, -y, -z) atoms [Cu-Br2: 3.079(2) angstrom], resulting in a tetragonally elongated octahedral structure for the CuO2N2Br2 coordination. The molecules form one-dimensional chains along the x-axis of the unit cell held together by intermolecular hydrogen bonds.
