The asymmetric unit of the title complex, (C6H8N)2[Cu(C7H3NO4)2]·6H2O, contains half a copper(II)–dipicolinate complex located on a twofold rotation axis, one protonated aniline mol­ecule and three solvent water mol­ecules. The CuII 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.
