Abstract
- The crystal structure of the title compound, [Cu(ClO4)2(C4H12N2)2], (I), is reported at 100, 250 and 400 K. The CuII cation in this complex is coordinated in a distorted octahedral mode characteristic of Jahn-Teller systems. The coordination of the perchlorate ligands via longer, and presumably weaker, axial Cu-O distances varies significantly as a function of temperature. One of the Cu-O distances increases between 100 and 250 K, and one of the Cu-O-Cl angles expands between 250 and 400 K. At all temperatures, the complex forms a two-dimensional N-H...O hydrogen-bond network in the (001) plane. [ABSTRACT FROM AUTHOR]
