History and structural properties Stannatrane

synthesis of stannatrane chloride , methyl stannatrane jurkschat , colleagues.




stereoscopic representation of methyl stannatrane crystal structure.


the crystal , molecular structure elucidated x-ray crystallography. x-ray diffraction study confirmed tricyclic ring structure , gave insight toward geometry of complex. tin-nitrogen distance of 2.624 Å, formal bond order calculated 0.46. presence of tin-nitrogen interaction, albeit weaker anticipated, led few key discoveries: (1) distortion ideal trigonal bipyramidal toward monocapped tetrahedron geometry; (2) lengthening of apical tin-methyl bond ~ 0.1 Å (largest known value existing tetraorganotin compounds); (3) observation of unusual hybridization @ apical tin-methyl bond.
