Abstract: | 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) Å, respectively. The benzene rings of the 2‐(2,3‐dichlorophenyl)amino]benzoate ligand subtend an angle of 50.49 (17)°; the conformation of the ligand is stabilized by intramolecular N—H?Cl and N—H?O hydrogen bonds. The structure is assembled viaπ–π stacking interactions to form chains parallel to 10]. |
