| Abstract: The structure of μ-oxygen-bis (tribenzyltin) single crystal was determined by X-ray diffraction method. The crstal belongs to trigonal with space group R3 and cell parameters: a=b=c=0.9646 nm, α=β=γ=83.99(1)°, V=0.8840 nm3, Z=1, Dx=1.503 g·cm-3, μ=14.473 cm-1, F(000)=402, final R=0.028 for 2288 unique reflection ［I≥3σ(I)］. The bond lengths of Sn-O is 0.1916 nm, all Sn-C bonds are 0.2168 nm. The bond angles of Sn-O-Sn is 180.00(0)°, furthermore, all O-Sn-C angles are between 108.16 and 108.25(9)°, and Sn-CH2-Ph angles are 110.8°, benzene ring plane atright angles. The six PhCH2 groups are oriented in staggered conformation. The structures of the title compound are symmetry on the oxygen atom. The base peak is the benzyl ion, that was formed by breaking the Sn-C bond in the mass spectrum. |
