摘要：

Three novel heterobimetallic polymers with Hg(SCN)(4)(2-) as a linker have been synthesised and characterized by means of IR, EPR, magnetic measurements and single crystal X-ray. All the obtained compounds [Cu(bpzm)Hg(SCN)(4)](n) (1), [Cu(bdmpzm)Hg(SCN)(4)](n) (2) and [Cu(dpa)Hg(SCN)(4)](n) (3) form supramolecular framework structures. The 1 creates a three-dimensional coordination polymer, and 2 and 3 form two-dimensional nets extending along crystallographic (0 1 0) plane. Each octahedrally coordinated Cu(II) atom of 1 connects to four mercury ions through four thiocyanate bridges, and each Hg(II) ion is bridged with four copper ions via four thiocyanate bridges. The CLOD ions of 2 and 3 display a pyramidal coordination geometry, and they are connected to three mercury ions through three thiocyanate bridges, one thiocyanate ion is nonbridging group.
