Pyrazolyl coordination polymers of cadmium(II)

The polymers [Cd(μ-Cl)2(pyrazole)2]n (1) and [Cd(μ-1,3-SCN)2(pyrazole)2]n (2) have been prepared and characterized. Both complexes exhibited chain structures made by linear arrays of Cd(II) bridged by chloro (1) or inversely related 1,3-SCN groups (2). Intermolecular hydrogen bonds and another non-covalent interactions are responsible for the self-assembly of linear chains into 2D networks.
