Synthesis, crystal structure and magnetic behavior of two cobalt coordination polymers with 1,2-bis(1,2,4-triazol-1-yl)ethane and dicyanamide

Synthesis, crystal structure and magnetic behavior of two cobalt coordination polymers with 1,2-bis(1,2,4-triazol-1-yl)ethane and dicyanamide [Co(bte)2(dca)2]n (1) and {[Co(bte)(dca)2] · H2O}n (2) have been synthesized and characterized by X-ray diffraction analyses and magnetic measurements. Compound 1 is a double-chain. In 2, each Co(II) center is bonded by two bridging bte ligands and four dca ligands as μ-1,5-dca in different orientations in the 3D network.
