摘要：

The mononuclear complexes [M(HmL)(2)(H2O)(2)], where M = Mn(II) (1), Ni(II) (2) or Zn(II) (3) and HmL = 2-methyllactato, were prepared and characterized by elemental analysis, FT-IR and UV/Vis spectroscopy and room temperature magnetic susceptibility measurements. Their thermal behaviour was also investigated, and compounds 1 and 3 were characterized by X-ray diffractometry. In both cases, the metal ion is hexacoordinated to two (O,O')-bidentate monoanionic 2-methyllactato ligands and two aqua ligands in a distorted octahedral fashion. The [M(HmL)(2)(H2O)(2)] units are connected by hydrogen bonds, forming a two-dimensional network. (C) 2003 Elsevier Science Ltd. All rights reserved.
