Abstract
The crystal structures of two molecular propellers are described. Enol phos phate 1 is triclinic P (1) over bar with a = 10.1110(4), b = 12.0647(6), c = 14.2112(7) Angstrom; alpha = 96.421(3), beta = 98.633(3), gamma = 108.594 (2) degrees and Z = 2. Enol phosphinate 2 is monoclinic P2(1)/n with a = 13 .527(3), b = 11.980(2), c = 17.326(3) Angstrom, beta = 98.616(9), degrees a nd Z = 4. Data from dynamic NMR investigations are in agreement with the si ze of the aryl torsion angles in the two enol propellers.
