Abstract: Silatrane Ibelongs to monoclinic system with space group P21/N(Z=4) and silatrane Ⅱ belongs to orthorhombic system with space group Pcab(Z= 8).The lattice parameters are.Ⅰ,α= 11.876(2)Å, 6=19.853(4)Å, c= 6.598(1)Å, β=110.12(2) Ⅱ.α= 19.653(4)Å, b=12.565(3)Å, c=12.570(3)Å.The structures were solved by RANTAN and refined by Full Matrix Least-Square Method. The final R-factors are 0.09 and 0.06, respectively.The N→Si bond of silatrane Iis shorter than that of Iand both of them are shorter than those of other kinds of silatranes.
