The central P atom of the title compound, C14H15OP, has a distorted te
trahedral environment, with a P-O bond length of 1.484 (2) angstrom an
d P-C bond lengths in the range 1.796 (2)-1.800 (3) angstrom. The O-P-
C angles vary from 111.6 (1) to 114.1 (1)-degrees and C-P-C from 105.2
(1) to 107.5 (1)-degrees.
