【 摘 要 】

The asymmetric unit of the title MOF, [Zn5(C14H5NO10S2)2(OH)2(H2O)10]n comprises three ZnII atoms, one of which is located on a centre of inversion, a tetra-negative carboxylate ligand, one μ3-hydroxide and five water molecules, each of which is coordinated. The ZnII atom, lying on a centre of inversion, is coordinated by trans sulfoxide-O atoms and four water molecules in an octahedral geometry. Another ZnII atom is coordinated by two carboxylate-O atoms, one hydroxy-O, one sulfoxide-O and a water-O atom to define a distorted trigonal–bipyramidal geometry; a close Zn...O(carboxylate) interaction derived from an asymmetrically coordinating ligand (Zn—O = 1.95 and 3.07 Å) suggests a 5 + 1 coordination geometry. The third ZnII atom is coordinated in an octahedral fashion by two hydroxy-O atoms, one carboxylate-O, one sulfoxide-O and two water-O atoms, the latter being mutually cis. In all, the carboxylate ligand binds six ZnII ions leading to a three-dimensional architecture. In the crystal, all acidic donors form hydrogen bonds to oxygen acceptors to contribute to the stability of the three-dimensional architecture.
