Abstract
A novel tetranuclear zinc(II) complex [Zn4Br4L2(H2L)], where L and H2L are the dianionic and zwitterionic forms of N,N′-bis(2-hydroxy-5-methoxybenzylidene)propane-1,3-diamine, is prepared and structurally characterized by elemental analysis, IR spectrum, and single crystal X-ray crystallography. The complex crystallizes in the monoclinic space group C2/c, with unit cell dimensions a = 38.338(2) Å, b = 10.5662(5) Å, c = 17.4607(8) Å, β = 113.767(2)°, V = 6473.3(6) Å3, Z = 4, R 1 = 0.0686, and wR 2 = 0.1752. The inner Zn atoms are five-coordinated in a square pyramidal geometry, and the outer Zn atoms are four-coordinated in a tetrahedral geometry. The intramolecular Zn⋯Zn distance is 3.103(1) Å.
