Synthesis and characterization of some new nickel(II), zinc(II) and cadmium(II) complexes of quadridentate SNNS ligands

Synthesis and characterization of bis(2-aminophenyl)disulphide diimine derivatives and their ruthenium complexes

“…Several diimine and diimine metal complexes have attracted considerable attention due to their widespread chemical and biochemical applications [1][2][3]. There has been considerable interest in the chemistry of metal complexes of ligands containing O,N; O,S; N,N; N,S and S,S donor atoms, owing to the industrial, carcinostatic, antitumour, antiviral and antimalarial activity of the complexes derived from them [4][5][6][7][8][9].…”

Spectroscopic, structural and magnetic studies of nickel(II) complexes with tetra- and pentadentate ligands

“…For complex 1 the highest energy d-d energy transition from the lower lying fully occupied 3d x 2 Ày 2 orbital to the upper empty 3d xy orbital ( 1 B / 1 A transition) at *430 nm is obscured by the MLCT transition. The other three lower energy d-d transitions from the occupied 3d z 2 , 3d xz , and 3d yz orbitals to the empty 3d xy orbital ( 1 B / 1 A, 1 B / 1 A and 1 A / 1 A transition, respectively) are less intense and appear as a broad envelope around the *625 nm region are typical of square planar monoligated nickel(II) complexes [29]. In addition, one MLCT transition is located at 400 nm.…”

Methyl 3-(4-Methoxyphenylmethylene)dithiocarbazate

“…In recent years, many metal complexes of sulfur-nitrogen chelating agents have been studied (Ali & Bose, 1984;Ali, Hossain, Majumder & Uddin, 1987;Simon, 1994). Aside from showing interesting physicochemical properties, some of these complexes have been found to display carcinostatic activity (Sunl, 1985).…”
