Synthesis, crystal structure and magnetic property of a one-dimensional Co(II) coordination polymer based on 1,1'-(2,2'-oxybis(ethane-2,1-diyl))bis(1H-1,2,4-triazole)

Abstract

A one-dimensional Co(II) complex [Co(BTE)2(NCS)2]n (1) (BTE = 1,1'-(2,2'-oxybis(ethane-2,1-diyl))bis(1H-1,2,4-triazole)) 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 one-dimensional chain polymer with a Co—Co separation of 8.830(2) Å. The adjacent 1D chain are linked by the π—π interaction between the triazole rings to form a two-dimensional layer parallel to the (0 0 1) crystal planes. Moreover, the thermal stability of the title complex is briefly investigated.
