摘要：
The crystal structures of two molecular propellers are described. Enol phosphate 1 is triclinic P 1¯ with a = 10.1110(4), b = 12.0647(6), c = 14.2112(7) Å; α = 96.421(3), β = 98.633(3), γ = 108.594(2)° and Z = 2. Enol phosphinate 2 is monoclinic P21/n with a = 13.527(3), b = 11.980(2), c = 17.326(3) Å, β = 98.616(9),° and Z = 4. Data from dynamic NMR investigations are in agreement with the size of the aryl torsion angles in the two enol propellers.
