[摘要]：A new germanium complex, cis-[Ge(pyca)(2)(OH)(2)]center dot 2H(2)O (1; pyca = pyridine-2-carboxylato), was synthesized by the reaction of [Ge(acac)(2)Cl(2)] (acac = acetylacetonato = pentane-2,4-dionato) with potassium pyridine-2-carboxylate (Kpyca) in H(2)O/THF. According to the single-crystal X-ray diffraction analysis, each Ge-atom of 1 is coordinated by two pyca ligands and two OH(-) groups (Fig. 1). These molecules are bonded to each other via a system of H-bonds resulting in a sheet-like structure (Fig. 2). The complex is decomposed during heating with stepwise mass loss and formation of GeO(2) as final product (Fig. 3).
