A Mercury(II) Mixed-Ligand Coordination Polymer Constructed from 4,7-Diphenyl- 1,10-Phenanthroline and Thiocyanate Ligands: Crystal Structure Studies, Spectroscopic Charactrization, And Thermal Analyses

Abstract

A new mixed-ligand coordination polymer [Hg(Ph₂phen)(μ_1,3-SCN)(SCN)]_n (1) is prepared from Hg(SCN)₂ and 4,7-diphenyl-1,10-phenanthroline (Ph2phen) in methanol. Suitable crystals for the X-ray diffraction measurement are obtained by methanol diffusion into a DMSO solution. Complex 1 is characterized by spectral methods (IR, UV-Vis, ¹³C{¹H}NMR, ¹H NMR, and luminescence), elemental analysis (CHNS), thermal analysis (TG, DTA), and single crystal X-ray diffraction. The structure of 1 is based on onedimensional zigzag chains running along the c axis. The luminescence spectrum shows stronger emission than that of free 4,7-diphenyl-1,10-phenanthroline.
