Structure of tetrakis((1,3-diethyl-2-thiobarbiturato)(butanol-1))dicobalt(II)

摘要

The structure of the dimeric complex [Co-2(BuOH)(4)(Detba)(4)] (I), where DeDetba is 1,3-diethyl-2-thiobarbituric acid, and BuOH is butanol-1, is determined (CIF file CCDC 1475273), and its IR spectrum is studied. The crystals are monoclinic: a = 10.7185(5), b = 21.985(1), c = 12.7235(7) , beta = 92.196(2)A degrees, V = 2996.1(3) (3), space group P2(1)/c, Z = 2. The Co2+ ions in compound I are joined in pairs by bridging ligands mu(2)-Detba(-)-O,O'. In addition, each of them is linked through the O atoms to one terminal Detba-ion and two BuOH molecules to form a trigonal bipyramid DD 3/4D(5). Hydrogen bonds O-H center dot center dot center dot O formed by BuOH and Detba(-) join the binuclear complexes into an infinite chain. The data of IR spectroscopy are consistent with the results of X-ray diffraction analysis.
