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)Cl2]·2CH3OH (1) (TIPT ¼ 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 Cl2 anions. This compound exhibits a three-dimensional solid-state structure constituted by N–H· · ·O, O–H· · ·Cl, N–H· · ·Cl and C–H· · ·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 g value is 8.26 £ 10230 esu. Its thermal properties were also determined in air. q 2004 Elsevier B.V. All rights reserved.
