摘  要:A new inorganic coordination compound Mn2Hg4(SCN)12 was synthesized. T he grown crystals were characterized by elemental analysis, infrared spectroscop ic analysis and powder crystal X-ray diffraction in detail. The crystal structur e of Mn2Hg4(SCN)12 was determined by single-crystal X-ray diffraction. It belong s to monoclinic system, P21/c space group. The cell dimensions are: a=1.171 6 nm , b=1.431 05 nm, c=2.105 1 nm, In the structure of it, ha lf of Mn2+ cations have five-coordinate number, and other half of Mn2+ cations h ave six-coordinate number; 3/4 of Hg2+ cations are coordinated by four SCN-, 1/4 of Hg2+ cations are coordinated by three SCN-and one NCS-, all the coordinatio n geometry of Hg2+ show slightly distorted tetrahedrons.
