Three new coordination polymers based on IB metal thiocyanates, [CuII(NCS)2(DMSO)4(meso-dpb)]n (1), [Cu2II(NCS)4(bpp)4]n (2), [CuI(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, CuII 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 MI 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.
