Metal Complexes in Biology and Medicine, V. — New Bismuth Hydroxycarboxylate Complexes. Synthesis and Structure of Bismuth(III) Malate Monohydrate and Bismuth(III) Tartrate Trihydrate Reaction of Bi(NO3)3 · 5 H2O with L‐(–)‐malic acid results in the formation of bismuth(III) malate monohydrate Bi[O2CCH2CH(O)CO2] · H2O (1) containing the tridentate ligand [L‐(–)‐malate]3– with all donating functions deprotonated. By way of contrast, reaction of Bi(NO3)3 · 5 H2O with L‐(+)‐tartraic acid gives bismuth(III) tartrate trihydrate (2), in which two different tartrate ligands, [L‐(+)‐tartrate]1– and [L‐(+)‐tartrate]2– are present. The solid‐state structures have been determined by single‐crystal X‐ray methods and confirmed by powder diffraction measurements. The structure analyses exhibit a three‐dimensional network in the crystalline state resulting from bridging and chelating properties of the polydentate hydroxycarboxylate ligands. Bismuth shows high coordination numbers.
