摘要：
The cobalt(II) complexes [Co(HL1)(2)(H2O)(2)].H2O) (1) and [Co(HL2)(2)(H2O)(2)] (2) [(HL1)(-) = (+/-)-lactate, (HL2)(-) = 2-Methyl- lactate] were prepared. and characterized structurally. The cobalt atom is in a distorted octahedral environment in both compounds. Both alpha-hydroxycarboxylato ligands are O,O'-bidentate chelating monoanions. The presence of a lattice water molecule in 1 makes its supramolecular organization different from that of 2. The thermal behaviour of both compounds was also investigated.
