In the title compound, [Cd(C8H4O4)(C 10H8N2O2)(H2O)] n , (I), each CdII atom is seven-coordinated in a distorted monocapped trigonal prismatic coordination geometry, sur-rounded by four carboxyl-ate O atoms from two different benzene-1,4-dicarboxyl-ate (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 inter-locked with each other, thus directly leading to the formation of a threefold inter-penetrated three-dimensional diamond architecture. To the best of our knowledge, (I) is the first example of a threefold inter-penetrating diamond net based on both bpdo and carboxyl-ate ligands. There are strong linear O - H...O hydrogen bonds between the water mol-ecules and carboxyl-ate 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 inter-penetrating diamond framework.
