A tetranuclear zinc-cerium complex: diaquaocta---methylacrylato-di--methylacrylatodipyridinediceriumdizinc

B. Wu and Y.-S. Guo

Abstract: In the title complex, a centrosymmetric carboxylate-bridged tetranuclear zinc-cerium derivative, [Zn₂Ce₂(C₄H₅O₂)₁₀(C₅H₅N)₂(H₂O)₂], the Ce^III and Zn^II ions are bridged by two bidentate carboxylato groups [CeZn 4.139 (1) Å], while the Ce ions are linked through the three bidentate carboxylate groups [CeCe 4.430 (1) Å]. The Ce atoms are nine-coordinate and the coordination polyhedron is a distorted tricapped trigonal prism. The Zn atoms are four-coordinate with a distorted tetrahedral geometry.
