Synthesis, structures and photoluminescence of thiocyanate bridged metal-organic polymers containing functional imidazole ligand

Three new coordination polymers, [Cd(SCN)2L2]n (1), [CdHg(SCN)4L2]n (2) and [MnHg(SCN)4L2]n (3) (L is trans-4-imidazolyl-4′-(N,N-diethylamino)stilbene) have been prepared and the complexes have been determined by X-ray crystallography. Complex 1 is a one-dimensional chain, and complexes 2 and 3 are two-dimensional frameworks.
