The crystal structure has been solved by the direct method and refined by the block-diagonal least-squares procedures to final R values of R_1=0.055 and R_2=0.047. The phosphorus atom of the Amiprophos molecule forms four tetrahedral covalent bends, of which the P-S bond exhibits rather high double bond character. It implies that the empty 3d-orbital of the phosphorus atom should be involved in the chemical bond formation. 胺草磷晶体,属三斜晶系,空间群为C_i~1-PI,晶胞中含两个分子,晶体学数据为:a=8.636(1),b=10.483(2),c=10.694(2)(?);α=110.92(1)°,β=111.27(1)°,γ=98.97(1)°;V=796.2(3)(?)~3,D_c=1.33g/cm~3,F(000)=336;μ(MoK_α)=3.2cm~(-1)。此结构用直接法解出,最后的R因子为:R_1=O.055,R_2=0.047。胺草磷分子中的磷原子形成四个四面体向的化学键,其中P—S键含有相当高的双键成分,这意味着磷原子的3d轨函参与成键。   << 更多相关文摘
