| Abstract: | The mono- and binuclear complexes Ni(Salen) (I) and Ni2(Salen)2 (II) (H2Salen = N,N′-bis(salicylidene)ethane-1,2-diamine), have been synthesized and structurally characterized by single-crystal X-ray diffraction
studies. The X-ray structural analyses show that the metal center of complex I is mononuclear and tetracoordinate with a distorted
tetrahedron, whereas the metal-centered complex II is binuclear and pentacoordinate with rectangular pyramid geometries, respectively.
The electrochemical studies evidenced for the mononuclear Ni(II) complex shows one quasireversible reduction potential at
−0.80 V (E
pc
) and the binuclear Ni(II) complex shows a reduction potential at −0.90 V (E
pc
) in the cathodic region.
