Abstract
The title polymeric complex of Cu(II) and Cd(II) bridged by thiocyanate, Cu(en)2[Cd(SCN)3]2, has been prepared and its structure determined by X-ray diffraction (XRD) methods. The crystal structure reveals that the Cu(II) atom is in an elongated octahedral coordination formed by two SCN− anions and two en molecules. The Cd(II) atom is in a distorted octahedral coordination formed by six bridging SCN− anions. Two different bridging thiocyanate anions exist in the complex. Both 1,1-μ-SCN− and 1,3-μ-SCN− anion act a role of bridge ligand and link Cu(II), Cd(II) atoms, and adjacent Cd(II). Cd(II) atoms form the three-dimensional (3-D) network polymeric structure. The IR and UV-Vis spectra have also been investigated.
