Aqua­chloro­[5-hydroxy­isophthalato(1−)](1,10-phenanthroline)copper(II) 2.5-hydrate

In the title compound, [Cu(C8H5O5)Cl(C12H8N2)(H2O)]·2.5H2O, the CuII atom is in a square-pyramidal geometry defined by one Cl− anion, one aqua O atom, one carbox­yl O atom belonging to one 5-hydroxy­isophthalate anion, and two N atoms from a 1,10-phenanthroline mol­ecule. O—H⋯O hydrogen bonds involving 5-hydroxy­isophthalate anions, the aqua ligands and the uncoordinated water mol­ecules, along with weak O—H⋯Cl hydrogen bonds, link the mononuclear units into a three-dimensional network structure.
