英文摘要：

The tide compound N, N, N＇, N＇ -tetra [ （diphenylphosphine） methyl ] -1,4-phenylenediamine is synthesized by reaction of [ Ph2 P （ CH2 OH） 2 ] Cl and 1,4-phenylenediamine. It is characterized by elemental analysis, IR, ^31 PNMR, ^1 HNMR. Single crystal X-ray diffraction analysis reveals that it is centro-symmetric with the inversion center at the centroid of phenylene. Intermolecular π-π stacking interactions between phenyl rings make molecules arrange along the b axis into one-dimensional chains, while these chains are further extended by intennolecular C-H…π interactions into three-dimensional supramolecular structure. The crystal is orthorhombic system with space group Pbca,Mr ： 900. 90,a = 12. 215（ 1 ） ,b = 14. 460（2） ,c =27. 821 （3） A,β =90℃,v =4914.0 （9）А^3 ,z =4,De = 1. 218 mg · m^-3 ,F（000） = 1896 ,R =0. 0487 ,wR = 0. 1245.
