Abstract
AbstractThe reactions of Cd(NO3)2·4H2O with NH4SCN and 2,4‐dpa (2,4‐dpa = 2,4‐dipyridineamine) in CH3OH afforded the one‐dimensional coordination polymer [Cd(NCS)2(2,4‐dpa)2]n, 1, while reaction of Cd(NO3)2·4H2O with NH4SCN and PmPa (PmPa = 2‐(1‐piperazinyl)pyrimidine) in CH3OH gave complex of the type [Cd(NCS)2(PmPa)2]n, 2. Each of the 2,4‐dpa ligand in complex 1 is coordinated to the Cd2+ metal center through pyridyl nitrogen atoms to form the one‐dimensional chain structures. The distorted {CdN4S2} octahedral coordination geometry around Cd2+ center is completed by pairs of bidentate thiocyanato ligands. Complex 2 has the 1‐D arrangement constructed through one‐dimensional double μ(N,S) end‐to‐end bridging thiocyanato groups bridged Cd(II) chains interconnected through PmPa ligands.
