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.

It belongs to tetragonal system, I (4) over bar space group. The cell dimensions are: a = 1.1324 (3) nm, c = 0.4270 (2) nm, V = 0.5475 (3) nm(3), Z = 2, D-c = 2.959 g/cm(3), R = 0.028, R-w = 0.037. The structure feature of the crystal is the Hg-S-C=N-Mn bridge which leads to the formation of an infinite three dimensional network. Irradiated by a 1064 nm Nd:YAG laser beam, MnHg (SCN), shows a 532 nm second harmonic intensity which is 18 times as that of organic nonlinear optical crystal urea, and therefore shows a quite promising application value as a useful nonliear optical material.展开更多
