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.
