Synthesis, structure and third-order nonlinear optical properties of 1,3,5-triazine-based Zn(II) three-dimensional supramolecule

A novel zinc(II) 1,3,5-triazine-based complex [Zn(TIPT)Cl-2].2CH(3)OH (1) (TIPT = 2,4,6-tri(2-ispropylidene-1-ly)hydrazono-1,3, 5-triazine) was prepared and structurally characterized by means of X-ray single crystal diffraction. The zinc(II) atom is coordinated at a distorted triangle bispyramid by three nitrogen atoms from TIPT and two Cl- anions. This compound exhibits a three-dimensional solid-state structure constituted by N-(HO)-O-..., O-(HCl)-Cl-..., N-(HCl)-Cl-... and C-(HCl)-Cl-... hydrogen bonds. The third-order nonlinear optical properties were determined by Z-scan techniques. The results indicate the compound exhibit strong self-focusing effect, and the hyperpolarizability gamma value is 8.26 X 10(-30) esu. Its thermal properties were also determined in air.
