In the title Ga III complex compound with pentetic acid, [Ga(C14 H20 N3 O10)(H2 O)]·3H2 O, the Ga III centre is bound in a slightly distorted octa-hedral coordination sphere by two amine N atoms, three carboxyl-ate O atoms and one water O atom. The complex mol-ecule exists as a zwitterion. In the crystal, the complexes are linked to each other via O - H ... O and C - H ... O hydrogen bonds, forming layers parallel to (001). Three uncoordinating water mol-ecules link the complex layers via O - H ... O, N - H ... O and C - H ... O hydrogen bonds, forming a three-dimensional network.
