摘要：

Dimethylaminodifluorophosphine, (CH3)2NPF2 (mp –87°), crystallizes with four formula units in an orthorhombic cell with a = 10.808 (12) Å, b = 7.601 (7) Å, and c = 6.259 (6) A at –110°. A total of 458 photographically recorded and visually evaluated X-ray data were used to determine the structure, which has been refined to R = 0.069. A space group ambiguity was resolved in favor of Pnma following leastsquares refinement in both Pnma and Pn21a and consideration of the effect of a slight scaling error in the weakest observed reflections. The molecule possesses mirror symmetry with the planar P-N-C skeleton lying in a crystallographic mirror plane. Bond lengths and standard deviations are P-N = 1.628 (5), P-F = 1.610 (4), and C-N = 1.460 (9) and 1.485 (8) Å. © 1969, American Chemical Society. All rights reserved.
