phosphorus heterocycle%Lawesson's reagent%crystal structure
The title compound, C31H30N3OPS3, crystallizes in monoclinic system, space group P21/n,with a = 11.839(7), b = 8.975(5), c = 29.15(2)A, β = 100.07(1)°, V = 3049(3)A3, Z = 4, Dc = 1.280g/cm3, Mr = 587.73, F(000) = 1232, μ = 0.324mm-1, the final R = 0.0434 and wR = 0.1140 for 4787 observed reflections with I >2σ(I). The title compound is a five-membered heterocycle containing a phosphorus, two nitrogen and two carbon atoms.The analysis result shows that the five-membered ring is nearly coplanar. The P(1)-N(1) bond length(1.685A) indicates the existence of p-dπ bond between N(1) and P(1) atoms of the title compound.
