Figure 1: (a) Anisotropic ellipsoid representation of complex 1. The ellipsoids are drawn at 50% probability level. Selected bond distances ( ) and bond angles (deg.): Sn1-O171 = 2.1069(18), Sn1-O172 = 2.5145(15), Sn1-O271 = 2.1086(15), Sn1-O272 = 2.577, Sn1-C31 = 2.086(3), Sn1-C41 = 2.091(3), O171-Sn1-O172 = 55.56(5), O172-Sn1-O272 = 83.39(6), and O271-Sn1-O171-C17 = 178.46(14). (b) Strong S bonding interaction leads to the formation of a dimer.
