Figure 3 Ball-and-stick model of the octahedral coordination sphere of Sn1; with exception of the hydrogen atoms, which are shown as spheres with common isotropic radius, all other atoms are represented as thermal displacement ellipsoids showing the 50% probability level of the corresponding atom; in cases (nBu, [mu]3-O, O2CCH3) that atoms form additional bonds these are drawn as shortened sticks to show the orientation.  [article HTML]
