Poly[diaqua-bis-[μ-1-hy-droxy-2-(imidazol-3-ium-1-yl)ethane-1,1-diyldiphospho-nato]tricopper(II)].

ABSTRACT: In the title coordination polymer, [Cu(3)(C(5)H(7)N(2)O(7)P(2))(2)(H(2)O)(2)](n), one Cu(II) atom is five-coordinated by five O atoms from three 1-hy-droxy-2-(imidazol-3-ium-1-yl)ethane-1,1-diyldiphospho-nate (L) ligands in a distorted square-pyramidal geometry. The other Cu(II) atom, lying on an inversion center, is six-coordinated in a distorted octa-hedral geometry by four O atoms from two L ligands and two O atoms from two water mol-ecules. The five-coordinated Cu(II) atoms are linked by phospho-nate O atoms of the L ligands, forming a polymeric chain. These chains are further linked by the six-coordinated Cu atoms into a layer parallel to (01). N-H⋯O and O-H⋯O hydrogen bonds connect the layers into a three-dimensional supra-molecular structure.
