Complexes of Mn(II), Cu(II) and Cd(II) with bipyridine isomers and lactates

The new mixed-ligand complexes containing bipyridine isomers and lactates with formulae Mn(2,4'-bpy)(2)(lact)(2)center dot 2H(2)O, Cu(2,4'-bpy)(2)(lact)(2), Cd(2,4'-bpy)(2)(lact)(2)center dot 2H(2)O, Cd(4-bpy)(lact)(2)center dot 2H(2)O (where: 2,4'-bpy = 2,4'-bipyridine, 4-bpy = 4,4'-bipyridine, lact = CH3CH(OH)COO-) were obtained. These complexes and metal lactates Mn(lact)(2)center dot 2H(2)O, Cu(lact)(2)center dot 2H(2)O and Cd(lact)(2)center dot H2O Were characterized by elemental analysis, IR, conductivity and magnetic measurements. The thermal behaviour of all compounds was studied by thermal analysis (TG, DTG, DTA) in air. A coupled TG/MS system was used to analyse the principal volatile products of thermolysis and fragmentation processes of Cu(II) compounds in air and argon.
