Сrystal structure and magnetic property of a new two-dimensional coordination polymer constructed by 1,4-bis(1,2,4-triazol-1-ylmethyl)-benzene and 4,4′-sulfonyldibenzoic acid

Abstract

A two-dimensional Ni(II) complex {[Ni(BTX)(SDBA)(H2O)]•0.29H2O}n (1) (BTX = 1,4-bis(1,2,4-triazol-1-ylmethyl)-benzene, H2SDBA = 4,4′-sulfonyldibenzoic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a two-dimensional polymer containing 28-membered rings based on the rhomboid subunit [Ni2(C14H8O6S)2] with a Ni–Ni separation of 12.923 A. The thermal stability and magnetic property of the title complex are briefly investigated.
