新型配合物Mn2Hg4(SCN)12的合成与晶体结构分析

A new inorganic coordination compound Mn₂Hg₄(SCN)₁₂ was synthesized. The grown crystals were characterized by elemental analysis, infrared spectroscopic analysis and powder crystal X-ray diffraction in detail. The crystal structure of Mn₂Hg₄(SCN)₁₂ was determined by single-crystal X-ray diffraction. It belongs 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, β=100.738°, and Z=4. In the structure of it, half of Mn²⁺ cations have five-coordinate number, and other half of Mn²⁺ cations have 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 coordination geometry of Hg²⁺ show slightly distorted tetrahedrons.
