• C<SUB>21</SUB>H<SUB>12</SUB>O<SUB>6</SUB>Cl<SUB>3</SUB>Zn<SUB>2</SUB>OH·2H<SUB>2</SUB>O crystallizes in the monoclinic space group P2<SUB>1</SUB>/c: <I>a</I>=12.779, <I>b</I>=23.732, <I>c</I>=14.749 Å, β=147.98°, and <I>Z</I>=4. The structure was determined by the usual heavy atom method and refined to <I>R</I>=0.039. The complex forms polymeric complex chains in the crystalline state. The ligands around two independent zinc atoms form an unusual trigonal bipyramid and an octahedron, respectively; the coordination geometry apparently differs from that found in the crystal structure of bis(2-chlorobenzoato) zinc(II). The correlation between coordination geometry and catalytic action of zinc atom is also discussed.
