Figure 2: (a) Anisotropic ellipsoid representation of complex 2. The ellipsoids are drawn at 50% probability level. Selected bond distances ( ) and bond angles (deg.): Sn1-O172 = 2.121(3), Sn1-O171 = 2.565, Sn1-O272 = 2.105(4), Sn1-O271 = 2.632, Sn1-C31 = 2.120(6), Sn1-C41 = 2.111(5), O172-Sn1-O272 = 81.66(13), O171-Sn1-O271 = 170.01, and O272-Sn1-O172-C17 = 177.6 . (b) Strong S bonding interaction leads to the formation of a dimer.
