| Abstract: | Two lactates and four new mixed ligand complexes with formulae Co(lact)2·2H2O, Ni(lact)2·3H2O, Co(4-bpy)(lact)2, Co(2,4'-bpy)2(lact)2, Ni(4-bpy)(lact)2·2H2O and Ni(2,4'-bpy)2(lact)2 (where 4-bpy=4,4'-bipyridine, 2,4'-bpy=2,4'-bipyridine, lact=CH3CH(OH)COO-) were isolated and investigated. The thermal behaviour of compounds was studied by thermal analysis (TG, DTG, DTA). In the
case of hydrated complexes thermal decomposition starts with the release of water molecules. The compounds decompose at high
temperature to metal(II) oxides in air. A coupled TG-MS system was used to analyse the principal volatile products of thermolysis
and fragmentation processes of obtained complexes.
This revised version was published online in July 2006 with corrections to the Cover Date. |
