摘      要：A novel terpyridine-based complex CdL＇S2 （L＇ = oxide of L; L = 10-hexyl-3-（2,6- di（pyridine-2-yl）pyridine-4-yl）-10H-phenothiazine） has been solvothermally synthesized and characterized by FT-IR spectroscopy, elemental analysis, 1HNMR and X-ray crystallography. The sulfur of phenothiazine moiety was oxidized when the crystal is formed. The complex C36H37CdN5O2S3 crystallizes in triclinic, space group P1 with a = 9.4452（9）, b = 13.0181（14）, c = 14.6721（18） A, a = 73.872（1）, β = 81.531（1）, y = 87.547（2）°, V= 1714.2（3） A3, Mr = 780.29, Dc= 1.512 ***-3,μ = 0.861 mm-l, F（000） = 800, Z = 2, the final R = 0.0456 and wR = 0.1059 for I 〉 2σ-（I）. The Cd（II） is coordinated by two terminal sulfur ions and three pyridyl nitrogen atoms in a distorted trigonal bipyramidal geometry. Universal hydrogen bonds between the neighboring molecules have generated a supramolecular arrangement which contributes to the stability of the title complex. Fluorescence property and thermogravimetry of the complex have also been investigated and discussed.
