Novel Thermally-Accessible Structural Distortion and Lattice Strain of a Chiral Cyanide-Bridged Cu ( II )-Ni ( II ) Complex

We have investigated temperature dependence of crystal structure of a chiral cyanide-bridged bimetallic assembly of [CuL2][Ni(CN)4]·2H2O (1) (L = (1R, 2R)-diaminocyclohexane). Cell parameters and most of bond distances decreased on cooling for 1. However, only a long Cu-N bond of semi-coordination increases on cooling, which is the first example of negative… CONTINUE READING
