Synthesis, crystal structure, and magnetic properties of a novel one-dimensional chain polymer based on 1-(4-nitrophenyl)-1,2,4-triazole

ABSTRACT

A one-dimensional Co(II) complex [Co(BPDC)(NPT)]_n (1) (H₂BPDC = benzophenone-2,4′-dicarboxylic acid, NPT = 1-(4-nitrophenyl)-1,2,4-triazole) has been synthesized and characterized using single crystal X-ray diffraction, IR and elemental analysis. Single-crystal X-ray diffraction analysis revealed that complex 1 is a one-dimensional double chain polymer based on [Co₂(OCO)₂] binuclear motif. The thermal stability and magnetic properties of complex 1 have been investigated, which revealed antiferromagnetic coupling interaction exists between Co(II) ions.
