主 题:cobalt(Ⅱ) complex crystal structure thermal stability analysis
摘 要:A one-dimensional chain cobalt(Ⅱ) coordination polymer with 2,4,6-trimethyl- benzoic acid, 4,4′-bipyridine and cobalt perchlorate anhydrous has been synthesized and characterized in the mixture solvent of water and alcohol. Crystal data for this complex: monoclinic, space group C2/c, a = 2.3805(8), b = 1.1464(4), c = 1.5807(5) nm, y = 128.435(4)°, V= 3.3791(18) nm^3, Dc = 1.246 g/cm^3, Z = 4, F(000) = 1340, final GooF = 1.009, R = 0.0504 and wR = 0.1287. Structural analysis shows that the cobalt ion is coordinated with two nitrogen atoms of one 4,4′- bipyridine molecule and four oxygen atoms from two 2,4,6-trimethylbenzoic acid molecules and two alcohol molecules, giving a distorted octahedral coordination geometry. The result of TG analysis indicates that the title complex is stable till 200 ℃.
