Synthesis of five new molybdenum(VI) thiosemicarbazonato complexes. Crystal structures of salicylaldehyde and 3-methoxy-salicylaldehyde 4-methylthiosemicarbazones and their molybdenum(VI) complexes

Polynuclear [MoO2{SalTSC-4-Me}]n, [MoO2{VanTSC-4-Me}]n and mononuclear [MoO2{SalTSC-4-Me}(CH3OH)], [MoO2{VanTSC-4-Me}(CH3OH)] and [MoO2{VanTSC-4-Me}(H2O)] · CH3CN complexes have been prepared by the reaction of [MoO2(acac)2] with salicylaldehyde 4-methylthiosemicarbazone or 3-methoxy-salicylaldehyde 4-methylthiosemicarbazone in acetonitrile or in dry methanol.
