Abstract

A series of cobalt (III) complexes containing 2-cyanoethylphosphines,[Co (Me 2 dtc) 2 {P (CH 2 CH 2 CN) n Ph 3− n} 2] BF 4 {Me 2 dtc−: N, N-dimethyldithiocarbamate; n= 1 (1), 2 (2), and 3 (3)} have been prepared, and their molecular structures in the crystals and in solution have been characterized. X-ray analysis revealed that all complexes isolated as single- crystals were the trans-isomers. The Co–P bond lengths for the 2-cyanoethylphosphines ...
