Poly[[[aqua(1,10-phenanthroline)cobalt(II)]-₃-4-bromoisophthalato] monohydrate]

X.-G. Hu and H.-P. Xiao

Abstract: In the title compound, {[Co(C₈H₃BrO₄)(C₁₂H₈N₂)(H₂O)]·H₂O}_n, each Co^II ion is six-coordinated by three O atoms from three carboxylate groups of three 4-bromoisophthalate dianions, one water molecule, and two N atoms from a 1,10-phenanthroline ligand. The coordination geometry around the Co^II cation is octahedral. Whereas the 1,10-phenanthroline ligand chelates to just one Co^II cation, the 4-bromoisophthalate dianions are bonded to three Co^II cations. The crystal structure is stabilized by several hydrogen bonds.
