Metallkomplexe in Biologie und Medizin, VI. Darstellung und Kristallstruktur von (Penicillaminato‐O,S,N)bismut(III)1‐chlorid

Metal Complexes in Biology and Medicine, VI[1]. – Synthesis and Structure of (Penicillaminato‐O,S,N)bismuth(III) Chloride Bismuth(III) oxychloride reacts with D‐(–)1‐penicillamine to form [D‐(–)1‐penicillaminato‐O,S,N]bismuth(III) chloride (1), the solid state structure of which has been determined by single‐crystal X‐ray diffraction. The tridentate chelation of the metal center by sulfur, nitrogen, and oxygen atoms leads to the formation of five‐membered rings. Due to interaction of bismuth with oxygen atoms of the carboxy groups, a polymeric two‐dimensional structure results in the crystal lattice. Bismuth has a seven‐fold inner coordination sphere.
