| Abstract: | Hydrothermal self-assembly has generated three coordination polymers incorporating the kinked hydrogen-bonding capable tethering ligand 4,4′-dipyridylamine (dpa) and the long flexible aliphatic dicarboxylate azelate dianion (−O2C(CH2)7CO2−, aze), M(aze)(dpa)(H2O)]n (M = Co, 1; M = Ni, 2) and {Cd(aze)(dpa)] · 2H2O}n (3). Complexes 1 and 2 possess crystallographically disordered azelate ligands, forming related three-dimensional (3-D) 4-connected “ligand vacancy” primitive cubic coordination polymer networks via the random intersection of two different types of M(aze)(dpa)]n idealized two-dimensional (2-D) layers. Compound 3 manifests a 3-D 658 CdSO4 topology coordination polymer network, formed from orthogonal sets of parallel Cd(aze)]n double chains linked through dpa ligands. Luminescent properties for 3 and thermal properties are also discussed. |
