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.
