A mixture of C10H7OPPh2 (1 g, 3.04 mmol) and elemental selenium (0.24 g, 3.04 mmol) in toluene (20 ml) was heated to reflux for 10 h and was then cooled to room temperature. It was then filtered and the solvent removed in vacuo to yield a pasty liquid which was dissolved in CH2Cl2 and layered with petroleum ether. Colorless crystals of the title compound were formed on standing overnight at 0 °C. Yield: 91% (1.12 g). Anal. Calcd. for C22H17OPSe: C, 64.87; H, 4.21%. Found: C, 64.63; H, 4.13%.
H atoms were placed in calculated positions with C—H = 0.95 Å and refined as riding contributions with Uiso(H) = 1.2Ueq(C).

Experimental. The diffraction data were obtained from 3 sets of 400 frames, each of width 0.5 °. in omega, colllected at phi = 0.00, 90.00 and 180.00 °. and 2 sets of 800 frames, each of width 0.45 ° in phi, collected at omega = -30.00 and 210.00 °. The scan time was 10 sec/frame. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

During the past few decades, charge transfer (CT) compounds have been the subject of extensive structural and theoretical investigations (Mague et al., 2007), and more recently, several groups have begun to investigate the role of phosphine chalcogenide CT compounds in the above areas (see, e.g. Cross et al. (1999) and Arca et al. (1999)). The present study is part of a structural investigation of phosphine chalcogenide ligands directed at obtaining a better understanding of the factors that influence bonding in these molecules which in turn may help predict the type of CT compounds they may form.
A perspective view of I is shown in Fig. 1. The distorted tetrahedral geometry about phosphorus is evidenced by the angles at phosphorus which range from 97.68 (8)° (O1—P1—C17) to 116.37 (5)° (O1—P1—Se1). The P═Se bond of 2.0890 (5) Å (Table 1) is shorter than 2.106 (1) Å found in Ph3P=Se (Codding & Kerr, 1979) because the replacement of one carbon on phosphorus by oxygen increases the effective electronegativity of the phosphorus atom thereby enhancing pπ-dπ back donation from a lone pair orbital of the chalcogen atom and shortens the P═Se bond. In the title compound the dihedral angles between the mean plane of the naphthyl group and mean planes of the phenyl rings built on C11 and C17 are, respectively, 80.97 (7) and 56.88 (7)° while that between the mean planes of the phenyl rings is 70.15 (8)°. The P1—O1—C1—C2 torsion angle is 173.8 (1)°.
