Abstract: The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex molecule solvated by two molecules of toluene in the asymmetric unit. The ZnII ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as [mu]3- and [mu]2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetrahedron, one EtZnO4 bipyramid and one ZnO6 octahedron, sharing common corners. The structure is stabilized by weak C-H...O and C-H...[pi] interactions.
