Abstract
A new method for preparing a molybdenum cysteinato complex with sulphur bridges is described. The complex was obtained from the system Most4 2-/ (HSCH2CII(NH2)COOH · HCl)/KOH with MeOH and water as solvents under dinitrogen atmosphere at ambient temperature. The complex crystallizes in the monoclinic system, space group P21 with unit cell parameters a = 7.0040(14) Å, b = 15.955(3) Å, c = 10.072(2) Å, B = 91.38°; V = 1125.2(4) Å3; Z = 2; Dc = 1.941 g cm−3; u = 18.9 cm−1. The final R = 0.0365 for 2219 observed reflections with I > 2 0 (I) and 277 parameters. The coordination polyhedron of molybdenum is distorted octahedral, and a terdentate cysteine ligand coordinates via N, S and O to the molybdenum atom.
