摘要
Crystal of the title compound Mr=304. 80 belongs to the triclinic, space group P1, with a = 7. 282)2), b=9. 064(2), c=11. 737(5) A , α=75. 79 (3), β=78. 70(3), γ=88. 49(2)°, V-736. 21 A3, Z=2, Dx = l. 375 g/cm3. The final refinement is converged with R=0. 062 and Rw= 0. 069.The five-membered heterocycle is in envelope conformation. The P - N bond length (1. 68(1)) indicates that the dπ-Pπ bond between P and N of the title compound is stronger than that of the corresponding 4-phenyl compound.
