Crystal structure and magnetic property of cobalt(II) assembled compound, {[Co(CA)(bipym)](H2O)(2)}(n) (H(2)CA = chloranilic acid, bipym=2,2'-bipyrimidine)
Cobalt(II) assembled complex compound, {[Co(CA)(bipym)](H2O)(2)}(n)(H(2)CA = chloranilic acid, bipym = 2,2'-bipyrimidine) (1) has been synthesized and structurally characterized by single-crystal X-ray diffraction. Compound 1 crystalizes in the monoclinic, space group C2/c(#15), with a = 16.652(4) Angstrom, b = 11.163(3) Angstrom, c = 10.081(3) Angstrom, beta = 116.12(2)degrees, V = 1682.4(7) Angstrom(3), Z = 4. The bipym ligands bridge the cobalt centers in bis-bidentate fashion and make zigzag chains. The chains form layer structures by stacking interaction and hydrogen bonding interaction with the help of interstitial water molecules. The temperature dependence of the magnetic susceptibility of 1 shows intramolecular antiferromagnetic interaction with theta = -39.7 K.
