Abstract

In the title compound, [Cu(C12H8N2)(C7H4SO5)(H2O)]·C3H7NO, the CuII atom has a square-pyramidal coordination geometry formed by three O atom and two N atoms. The 1,2-di-4-pyridylethyl­ene ligands function as μ2-bridging ligands to form a zigzag chain. The 2-sulfonatobenzoate ligands protrude on alternate sides of the chain. Inter­molecular O—H⋯O hydrogen bonds link the chains into a two-dimensional network structure. [ABSTRACT FROM AUTHOR]

Abstract

In the title compound, [Cu2(C8H4O5)2(C12H8N2)2(H2O)2]·3H2O, the Cu complex forms a centrosymmetric dimer with a Cu⋯Cu separation of 8.198 (3) Å. In the 5-hydroxy­isophthalate ligands, two carboxyl­ate groups coordinate two copper(II) cations in μ2-bridging bidentate coordination modes. [ABSTRACT FROM AUTHOR]
