Synthesis, Crystal Structure, and Luminescence Property of a New Zinc(II) Complex With Schiff-Base Containing Triazole Propane Ancillary Ligand

Abstract

A new binuclear zinc complex, namely [Zn(Salpn)₄(1,3-btp)]_n (1, H₂salpn = N,N′- bis(salicylidene)-1,3-diaminopropane, while 1,3- btp = 1,3-bis (triazole) propane) has been synthesized under one-pot reaction conditions in high yield, and has been characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. The complex 1 crystallizes in the monoclinic system, space group of C2/c with a = 18.2270(17), b = 10.7435(10), c = 20.2896(19) Å, β = 92.9780(10)°. The two adjacent zinc-Salpn moieties were connected through the flexible 1,3-btp ligand into a binuclear unit. The bulk purity of the materials of 1 was confirmed through the powder X-ray diffraction (PXRD) experiments. Furthermore, the luminescent property of the complex 1 has also been investigated.
