文摘

Six new bicycloazastannoxides have been synthesized. The coordination pattern at the Sn(IV) center was established by X-ray diffraction. Tbp geometry was noted for Me2Sn(L1H), nBu2Sn(L1H), Ph2Sn(L1H), Bz2Sn(L1H) and Ph2Sn(L3H). Trigonal-prismatic polyhedron was observed for [Me2Sn(L2H)(MeOH)]·MeOH (5). Molecules in 5 associates to give 22-membered macrocycles via Sn⋯O and O-H⋯O contacts.
