摘要
The self-assembly reaction of zinc ions with tetracyanometalates in the presence of the tridentate chelated ligand 2,2:6,2-terpyridine (terpy) yielded three cyanide-bridged bimetallic compounds of general formula Zn(terpy)(H2O)M(CN)(4) [M = Ni (1), Pd (2), Pt (3)]. Compounds 1-3 were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR), and thermogravimetric (TG) analysis. Single-crystal XRD analysis revealed that compounds 1-3 are isostructural and the structure consists of [Zn(terpy)(H2O)](2+) moieties and [M(CN)(4)](2-) units linked alternatively to generate a one-dimensional (1D) linear chain. The chains are further connected together through hydrogen bonding and - stacking interactions, forming a 3D supramolecular network. IR spectroscopic analysis indicated the presence of cyanide groups and terpy ligands in the structure. TG and powder XRD results showed that compounds 1-3 have higher thermal stabilities and exhibited irreversible for desorption/resorption of one coordinated water molecule.
