Crystal Structure and Third-Order Nonlinear Optical Property of a Cadmium Complex Constructed by 1,3-Dithiole-2-Thione-4,5-Dithiolato Ligand

Abstract

A cadmium complex constructed by the ligand 1,3-dithiole-2-thione-4,5-dithiolato (DMIT) has been synthesized and its structure has been determined by means of X-ray single crystal diffraction. Crystal data for this complex are as follows: monoclinic, space group Cc, a ¼ 24.590(2), b ¼ 8.7882 (7), c ¼ 13.8032(11) Å , b ¼ 116.3350(10) , V ¼ 2,673.3(4) Å 3 , Z ¼ 4, F(000) ¼ 1,188. The central cadmium ion coordinates with two DMIT which constructed a distorted tetrahedron. Its third-order nonlinear optical property has been studied using Z-scan technique with 20 ps pulses at wavelength 1,064 nm. Its molecular second hyperpolarizability c was determined to be 3.96 Â 10 À55 C.m 4 =V 3 .

Synthesis and crystal structure of a new 2D supramolecular Cd(II) complex with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone ligand

“…Moreover, HPMBP has two O atoms, two N atoms, and two phenyl rings, and its hydrogen bonds network and other weak interactions can be formed (Cheng et al, 2014). The Cd(II) atom, as a IIB group metal ion, has a 4d 10 electron configuration and displays flexible coordination numbers (Sun et al, 2005;Hu and Li, 2010;Nie et al, 2010;Calatayud et al, 2013;Sharif and Najafi, 2013). In addition, some Cd(II) complexes show good fluorescent (Nie et al, 2010;Pathak et al, 2012;Calatayud et al, 2013) and antimicrobial (Zaky et al, 2012) properties.…”
