title: Dieth-yl(μ3-2-methyl-4-oxo-4H-pyran-3-olato-κ(4) O (3),O (4):O (3):O (3))tris-(μ2-2-methyl-4-oxo-4H-pyran-3-olato-κ(3) O (3),O (4):O (3))trizinc toluene disolvate.
abstract: The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetra-hedron, one EtZnO4 bipyramid and one ZnO6 octa-hedron, sharing common corners. The structure is stabilized by weak C-H⋯O and C-H⋯π inter-actions.
