Equimolar quantities of Mo(CO)6, triphenylphosphine and 1,10-phenanthroline were refluxed in toluene under an N2 atmosphere for seven hours. After cooling, air-stable black slabs and blocks of (I) were recovered by vacuum filtration and rinsing with light petroleum ether in 79% yield based on Mo(CO)6. The crystals of (I) smear to a deep orange colour on a glass slide.
The hydrogen atoms were geometrically placed (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).
The title compound, (I), Mo(CO)3(C18H15P)(C12H8N2), is an example of a trisubstituted group-6 metal hexacarbonyl (Howie & McQuillan, 1986). The related tricarbonyl-triphenylphosphine-2,2-bipyridyl-molybdenum(0) is described in the next paper (Muir et al., 2007).
The three remaining carbonyl groups atached to the Mo atom in (I) form one face of the distorted MoC3N2P octahedron. Otherwise, all the bond lengths and angles in (I) (Fig. 1) may be regarded as normal (Allen et al., 1987). The diehdral angles for the phenyl rings for the triphenylphosphine molecule are C16—C21/C22—C27 = 83.94 (11)°, C16—C21/C28—C33 = 71.77 (12)°, and C22—C27/C28—C33 = 67.95 (12)°. The N—Mo—N bite angle for the 1,10-phenanthroline (phen) molecule is 73.48 (5)°.
There is a slight distinction between the shorter Mo1—C2 and Mo1—C3 bond lengths trans to N atoms and and the longer Mo1—C1 bond, which is trans to the P atom. The traditional explanation (Cotton & Wilkinson, 1966) for this phenomenon is that triphenylphosphine is a π-acceptor ligand and completes for metal d electrons with the carbonyl group trans to itself, hence the Mo—C bond has less double-bond character than a Mo—C bond trans to an atom with no π-acceptor properties such as N, and is therefore longer. The C1—Mo1—P1 bond angle is also closer to linear than the C—Mo—N angles.
In the crystal of (I), a rather short C—H···O interaction arising from a phen C—H grouping (Table 2) may help to establish the packing.

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. |

The title compound, (I), Mo(CO)3(C18H15P)(C12H8N2), is an example of a trisubstituted group-6 metal hexacarbonyl (Howie & McQuillan, 1986). The related tricarbonyl-triphenylphosphine-2,2-bipyridyl-molybdenum(0) is described in the next paper (Muir et al., 2007).
The three remaining carbonyl groups atached to the Mo atom in (I) form one face of the distorted MoC3N2P octahedron. Otherwise, all the bond lengths and angles in (I) (Fig. 1) may be regarded as normal (Allen et al., 1987). The diehdral angles for the phenyl rings for the triphenylphosphine molecule are C16—C21/C22—C27 = 83.94 (11)°, C16—C21/C28—C33 = 71.77 (12)°, and C22—C27/C28—C33 = 67.95 (12)°. The N—Mo—N bite angle for the 1,10-phenanthroline (phen) molecule is 73.48 (5)°.
There is a slight distinction between the shorter Mo1—C2 and Mo1—C3 bond lengths trans to N atoms and and the longer Mo1—C1 bond, which is trans to the P atom. The traditional explanation (Cotton & Wilkinson, 1966) for this phenomenon is that triphenylphosphine is a π-acceptor ligand and completes for metal d electrons with the carbonyl group trans to itself, hence the Mo—C bond has less double-bond character than a Mo—C bond trans to an atom with no π-acceptor properties such as N, and is therefore longer. The C1—Mo1—P1 bond angle is also closer to linear than the C—Mo—N angles.
In the crystal of (I), a rather short C—H···O interaction arising from a phen C—H grouping (Table 2) may help to establish the packing.
