Poly[aqua(,2 -benzene-1,4-dicarboxylato)(,2 -4,4,-bipyridine N,N,-dioxide)cadmium(II)], a threefold interpenetrating diamond net

ACTA CRYSTALLOGRAPHICA SECTION C, Issue 8 2010
Guohai Xu
In the title compound, [Cd(C8H4O4)(C10H8N2O2)(H2O)]n, (I), each CdII atom is seven-coordinated in a distorted monocapped trigonal prismatic coordination geometry, surrounded by four carboxylate O atoms from two different benzene-1,4-dicarboxylate (1,4-bdc) anions, two O atoms from two distinct 4,4,-bipyridine N,N,-dioxide (bpdo) ligands and one water O atom. The CdII atom and the water O atom are on a twofold rotation axis. The bpdo and 1,4-bdc ligands are on centers of inversion. Each crystallographically unique CdII center is bridged by the 1,4-bdc dianions and bpdo ligands to give a three-dimensional diamond framework containing large adamantanoid cages. Three identical such nets are interlocked with each other, thus directly leading to the formation of a threefold interpenetrated three-dimensional diamond architecture. To the best of our knowledge, (I) is the first example of a threefold interpenetrating diamond net based on both bpdo and carboxylate ligands. There are strong linear O,H...O hydrogen bonds between the water molecules and carboxylate O atoms within different diamond nets. Each diamond net is hydrogen bonded to its two neighbors through these hydrogen bonds, which further consolidates the threefold interpenetrating diamond framework. [source]
