Nitric oxide generation study of unsymmetrical β-diketiminato copper() nitrite complexes
β-Diketiminato copper( ii ) L 1 CuCl- L 4 CuCl and their nitrite complexes L 1 Cu(O 2 N) and L 2 Cu(O 2 N) have been synthesized and characterized. X-ray analysis of the L 1 CuCl- L 4 CuCl complexes clearly reveals their mononuclear structure with a four-coordinated Cu( ii ) center bound by one chlo...

CuCl complexes clearly reveals their mononuclear structure with a four-coordinated Cu(
