Two dinuclear succinato-bridged nickel(II) complexes [Ni(RR-L)] 2 (μ-SA)(ClO 4 ) 2 (1) and [Ni(SS-L)] 2 (μ-SA)(ClO 4 ) 2 (2) (L = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane, SA = succinic acid) were synthesized and characterized by EA, Circular dichroism (CD), as well as IR and UV/Vis spectroscopy. Single crystal X-ray diffraction analyses revealed that the Ni II atoms display a distorted octahedral coordination arrangement, and the succinato ligand * Dr. G. C. Ou
