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)(H_2O)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)(H_2O)]~(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 π–π 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.
