The synthesis, crystal structure and spectroscopic properties of luminescent Zn(II) complex

A luminescent Zn(II) complex 1, ZnL2Cl2·2H2O has been synthesized where L = 2,2′,2″-(1,3,5-benzenetriyltrimethylidyne) as a yellow crystal. Single crystal X-ray analysis of the compound 1 shows a distorted tetrahedral structure. The compound 1 crystallizes in monoclinic, space group C2/c with a = 20.3151(19), b = 8.7299(9), c = 24.626(2) Å, β = 107.474(2)°, V = 4165.9(7) Å3. At room temperature, the complex 1 exhibits an intense blue emission at 474 nm upon 380 nm excitation.
