A P,O,P′-tridentate mixed-donor scorpionate ligand:: 6-[4,6-bis(diphenyl-phosphino)-10H-phenoxazin-10-yl]hexan-1-ol

The title compound, C(42)H(39)NO(2)P(2), is a P, O, P '-tridentate scorpionate-type ligand and has one molecule in the asymmetric unit. The angles involving the P atoms range from 100.21 (7) to 104.89 (7)degrees. The N-hexanol group was found to be disordered and was refined over two positions with final occupancies of 0.683 (3) and 0.317 (3) which affected the C-O and C-N bond lengths. The bond lengths for C-O range from 1.402 (2) to 1.415 (2) angstrom and for C-N from 1.410 (2) to 1.448 (3) angstrom for the major disorder component; the corresponding ranges for the minor disorder component are 1.429 (3)-1.408 (3) and 1.474 (3) - 1.474 (4) angstrom.
