Synthesis and Crystal Structure of N,N’,N’’-Tris-(2-aminophenyltriphenylphosphium)-benzene-1,3,5-tricarboxamide

【摘要】 A new tripodal P,N ligand (C63H48N3O3P3) was prepared and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 13.013(3), b = 28.406(6), c = 14.911(3) , β = 111.04(3)o, V = 5144.6(18) 3, Z = 4, Dc = 1.276 g/cm3, Mr = 987.95, λ(MoKα) = 0.71073 , μ = 0.17 mm-1, F(000) = 2064, R = 0.0786 and wR = 0.1545. A total of 43260 unique reflections were collected, of which 5112 with I > 2σ(I) were observed. The title compound has a central benzene ring, which is linked by -NH-CO- bonds to three 2-aminophenyltriphenylphosphium moieties, of which two with P(1) and P(2) centers are pointing to the same face of the central aryl ring, while the third one directs oppositely, forming a pseudo-propeller. In the crystal structure, there exist face-to-face π-π stacking interactions which increase the stability of the crystal structure.更多还原
