A tetranuclear zinc benzoate Zn 4O(C 6H 5CO 2) 6 was synthesized and characterized by X-ray single crystal determination. It crystallizes in cubic, space group Ia-3d. Its crystal cell is very large, a= 4.100 63(18) nm, V= 68.953(5) nm 3 and Z = 48. The structure is composed of discrete Zn 4O(C 6H 5CO 2) 6 molecules. In each molecule, four zinc atoms are held together by a central oxygen atom, which results in the formation of a regular tetrahedron. All benzoate ligands coordinate to zinc atoms in a bidentate bridging mode. Each zinc atom is in a slightly distorted tetrahedral geometry, coordinated by three benzoate oxygen atoms and the central oxygen atom. The intermolecular interactions result in the formation of a three-dimensional supramolecular framework, with non-intersecting parallel channels.
