摘要
The crystal structure of 2-nitrophenyl N,N-bis（2-chloroethyl）-N＇-（4-methylbenzene-sulfonamino）ethyl-phosphorodiamidate （C19H25Cl2N4O6PS） was determined by single-crystal X-ray diffraction analysis. The compound crystallizes in the triclinic system, space group PI^- with a = 9.3664（13）, b = 9.9560（14）, c = 13.1803（18） ,A, α = 87.338（2）, β= 87.632（2）, γ = 79.536（2）°, Dc = 1.484 g/cm^3, Z = 2, λ = 0.71073 A, μ（MoKα） = 0.465, Mr = 539.36, V = 1206.7（3） A^3, F（000） = 560, the final R = 0.0426 and wR = 0.1097 for 3463 observed reflections with I 〉 2σ（I）.
