Bis{mu-2-[(2,3-dichlorophenyl)amino]benzoato-kappaO}di-mu2-ethoxo-octamethyldi-mu3-oxo-tetratin(IV).
The title compound, [Sn4(CH3)8(C13H8Cl2NO2)2(C2H5O)2O2], is a centrosymmetric dimer, with three linearly fused four-membered Sn-O-Sn-O rings. The coordination polyhedron of the Sn atom bonded to the carboxylate can be described as trigonal-bipyramidal distorted toward square-pyramidal. That of the second Sn atom is similar, but the distortion towards square-pyramidal geometry is greater. The Sn-O and Sn-C distances are 2.020 (2)-2.226 (2) and 2.096 (4)-2.114 (4) A, respectively. The benzene rings of the 2-[(2,3-dichlorophenyl)amino]benzoate ligand subtend an angle of 50.49 (17) degrees; the conformation of the ligand is stabilized by intramolecular N-H...Cl and N-H...O hydrogen bonds. The structure is assembled via pi-pi stacking interactions to form chains parallel to [120].
