The title compound, C 30 H 28 N 6 Á2H 2 O, is an example of a new N-donor neutral organic ligand. The asymmetric unit consists of two half-molecules (organic) and two water molecules; each independent organic molecule is centrosymmetric. The water molecules are linked by O-HÁ Á ÁO hydrogen bonds, fo
