| Abstract: | Four heterometallic tartratogermanate complexes, namely Cu2Ge2(Tart)3(H2O)10] n · 3nH2O and (H3O)LnGe2(Tart)3(H2O)6] · nH2O (Ln3+ = Gd, n = 3.5; Tm, n = 3; Yb, n = 3), have been prepared via the reaction between germanium tetrachloride and D-tartaric acid (H4Tart) in aqueous acetic acid. All complexes contain {Ge2(Tart)3} n 4n- polymer chains. The Cu2+ and Ln3+ atoms coordinate only Tart carbonyl oxygen atoms. |
