Three new coordination polymers based on IB metal thiocyanates, [Cu-II(NCS)(2)(DMSO)(4)(meso-dpb)](n) (1), [Cu-2(II)(NCS)(4)d(bpp)(4)](n) (2), [Cu-I(NCS)(pia)](n) (3) (dpb = 2,3-di(4-pyridyl)-2,3-butanediol, bpp = 1,3-bis(4-pyridyl) propane, pia = N,N'-(1,2-phenylene)diisonicotinamide), have been synthesized by the pre-assembly method and characterized by X-ray crystallography. In 1, Cu-II cations are bridged by meso-dpb ligands to form a one-dimensional (1D) linear chain. Compound 2 consists of 2D undulated layers of (4, 4) topology that show twofold parallel interpenetration. In the case of 3, the M-I center adopts tetrahedral coordination geometry and the 2D networks are formed by organic ligand with "folding ruler-shaped" NCS - M chains. The thermal properties of 1-3 were also investigated. (C) 2008 Published by Elsevier B.V.
