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

X-ray diffraction studies established the structure of the palladium complex, PdL2. The geometry of Pd (II) in the complex is close to square planar and in novel cis-configuration with two ferrocene moieties on the same side. Degenerate four-wave mixing (DFWM) measurements show that the complex exhibit obvious nonlinear optical response.展开更多

The Schiff base ligand acts as a single negatively charged bidentate ligand fondng D-M-D type comPlex (D=donor, M=metal). Single crystal X-ray diffraction analysis of the copper(Ⅱ) complex established that the geometry around Cu (Ⅱ) is square-planar with two equivalent M-N and M-S bonds. The two phenyl rings and the coordinated plane are almost in one plane fotheng an electronic delocalization system. Their thirdorder response was also studied.展开更多
