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

摘要

A new mixed-ligand coordination polymer [Hg(Ph(2)phen)((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, C-13{H-1}NMR, H-1 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.
