A Hydrated Schiff Base Derivative of Bis(acetylacetone)ethylenediimine with 2-Pyridinylethyl Side Chains

3,10-Bis[2-(2-pyridinyl)ethyl]-4,9-dimethyl-5,8-diazadodeca-4,8-diene-2,11-dione, C₂₆H₃₄N₄O₂, exists as a keto-amine tautomer, i.e. the 3,9-diene. There are two independent molecules in the triclinic unit cell, each located on a crystallographic inversion center. The orientation of the pyridine rings creates a pseudo-inversion center midway between the molecular centers. Eight water molecules are also present in the unit cell.
