Abstract: Three title compounds were prepared and the structure of title compound 2 was characterized by IR, 1H NMR, 13C NMR, 119Sn NMRspectroscopy and the crystal structure of compound 2a was determined by Xray analysis with the final Rindices[ I>2σ(I)] R1=0.0350 and R2,ω=0.0888. The crystal of compound 2a belongs to triclinic system, space group P1 with a=10598(6) nm, b=13074(10) nm, c=13786(10) nm, α=62666 (7)°, β=72530(2)°, γ=80680(2)°, V=16180 nm3, Dx=1444 g·cm-3, Z=1, F (000)=728. The bond length of Sn1_O1 is 0.2076 nm and Sn 1... O2 distance is 0.3013 nm. The coordination about the tin atom can be considered as a distorted tetrahedral. The detail values of 1H NMR, 13C NMR, 119Sn NMR, 2J 119Sn1Hand J 119Sn13 Cwere obtained. δ 119Sn=23.836, 2J 119Sn1H=88.0 Hz, 1J 119Sn13 C=347.1 Hz, 2J 119Sn13 C=45.6 Hz.
