Three new coordination polymers with 1,2,3-triazolate ligands, [Cd-3(ta)(3)Cl-3](n) (1), {[Cd-3(ta)(6)] center dot 6H(2)O}(n) (2) and [Cu-6(ta)(3)I-3](n) (3) (Hta = 1,2,3-triazole), have been hydrothermally synthesized and structurally characterized. In complex 1, the Cd2+ and Cl- ions form a 3D [(Cd3Cl3)(3+)](n) inorganic framework with (8(2).12)(4.8.10) topology while the Cd2+ ions and ta(-) ligands give a {[Cd-3(ta)(3)](3+)}(n) double helical chain. The two moieties are fused with each other by sharing hinge Cd2+ ions leading to a 3D organic inorganic hybrid structure. The 3D porous metal-organic framework of complex 2 shows the topology of the diamond net with the Cd-centered CdCd4 tetrahedron units as the connecting nodes. The desolvated structure of 2 has 48% solvent accessible space of the total volume. Complex 3 is an undulating 1D organic-inorganic hybrid complex consisting of interesting discrete five-capped [Cu6I5](-) triangular prism clusters and arched metallacycle [Cu-6(ta)(6)I](+) moieties.
