Crystal structure study of Co(II) complexes with 2,2′-(1,4-ethylenedioxyl) dibenzoic acid-[Co · L · (H2O)3]n · nH2O · 0.2 nH2O

Abstract

The structure of the title complex [Co·L·(H2O)3]n·nH 2O·0.2 nH2O has been established by single crystal X-ray diffraction. Crystals of the complex are monoclinic, space group C2/c with cell constants a = 45.29(4), b = 10.031(6), c = 8.015(6) Å, β = 90.65(8)°, Z = 8, Dc = 1.489 g·cm-3. The structure was solved and refined to R =0.0478 (wR = 0.0577). In the chain structure, Co(II) ions are hexacoordinated by O atoms in an octahedral arrangement. CoO6 octahedra share corners (bridged) through O atoms of water, with each L2--ligand binding two adjacent Co atoms.
