Dianilinium bis­(pyridine-2,6-dicarboxyl­ato-κ3 O 2,N,O 6)cuprate(II) hexa­hydrate

The asymmetric unit of the title complex, (C 6 H 8 N) 2 [Cu(C 7 H 3 NO 4 ) 2 ]·6H 2 O, contains half a copper(II)–dipicolinate complex located on a twofold rotation axis, one protonated aniline mol­ecule and three solvent water mol­ecules. The Cu II atom is coordinated by four O atoms and two N atoms from two dipicolinate ligands in a distorted octa­hedral environment. In the crystal, the components are linked into a three-dimensional framework by inter­molecular O—H⋯O and N—H⋯O inter­actions.
