The dinuclear title compound, [Zn(2)(C(19)H(17)N(3)O(2))(2)(H(2)O)(2)]·4C(2)H(6)OS, lies about a center of inversion. The deprotonated monoanion O,N,O-chelates the Zn atom; the hydr-oxy 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 mol-ecule. Hydrogen bonds, with the water mol-ecule 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.
双核标题化合物[Zn₂(C₁₉H₁₇N₃O₂)₂(H₂O)₂]·4C₂H₆OS具有一个对称中心。去质子化的单阴离子O,N,O-螯合Zn原子；羟基O原子也与对称相关的Zn原子形成键合，使得一个N原子和三个O原子围绕金属形成一个正方形。配位几何形状为四方锥，顶端位置被一个水分子占据。以水分子作为供体原子的氢键导致形成线性链状结构单元。在配合物分子和溶剂O原子之间存在一个N-H⋯O氢键。
