Abstract
The dinuclear title compound, [Zn2(C19H17N3O2)2(H2O)2]·4C2H6OS, lies about a center of inversion. The deprotonated monoanion O,N,O-chelates the Zn atom; the hydroxy O atom also engages in bonding to the symmetry-related Zn atom so that one N and three O atoms form a square around the metal. The coordination geometry is square-pyramidal, with the apical site occupied by a water molecule. Hydrogen bonds, with the water molecule serving as donor atom, lead to the formation of a linear chain motif. There is an N—H⋯O hydrogen bond between the complex molecule and solvent O atom.
