Reaction of the tricarbonyl{η5-[2-(dimethylamino)ethyl]cyclopentadienyl}molybdenum anion and dichloridodiphenylstannane affords the title compound, [MoSn(C6H5)2Cl(C9H14N)(CO)3], which exhibits a four-legged piano-stool geometry with chloridodiphenylstannyl ligands unperturbed by the pendant 2-(dimethylamino)ethyl groups. The Mo—Sn bond length [2.7584 (5) Å] and the distortion of the tetrahedral tin coordination geometry are similar to those observed in related tin-substituted tricarbonylmolybdenum and -tungsten complexes.

The of coordinatively saturated chlorostannyl ligands has been explored by Tang et al. (2005). Structural parameters that define four-legged piano-stool geometries were detailed by Kubácek et al.

The following procedures were conducted under argon using standard techniques for handling air and moisture sensitive substances. THF (75 ml) was added to molybdenum hexacarbonyl (0.415 g, 1.57 mmol) and sodium ((2-dimethylamino)ethyl)cyclopentadienide (0.300 g, 1.88 mmol). The yellow solution was refluxed for 15 h. Addition of dichlorodiphenylstannane (0.540 g, 1.57 mmol) in THF (30 ml) resulted in a pale yellow suspension. A single molybdenum carbonyl complex was present in solution (based on IR spectroscopy) within 10 min. The suspension was filtered through Celite. THF was removed in vacuo revealing a yellow oil. The product was extracted with pentane (5 * 70 ml). Each colorless extract was filtered. The combined extracts were concentrated in vacuo until a yellow solid precipitated. The suspension (75 ml) was cooled and filtered at -70°C. The pale yellow, moderately air-sensitive solid was washed with pentane (-60°C, 5 * 15 ml) and dried in vacuo. Recrystallization from pentane at -65°C afforded pale yellow microcrystals (0.461 g, 47%). X-ray quality single crystals of 1 were obtained from a supersaturated pentane solution.
The structure was solved using Bruker SHELXTL and refined using Bruker SHELXTL. The
was determined based on and intensity statistics. A direct-methods solution was calculated which provided most non-hydrogen atoms from the E-map. Full-matrix least squares / difference Fourier cycles were performed which located the remaining non-hydrogen atoms. All non-hydrogen atoms were refined with anisotropic displacement parameters. All hydrogen atoms were placed in ideal positions and refined as riding atoms with relative isotropic displacement parameters. The final full matrix least squares converged to R1 = 0.0362 and wR2 = 0.0827 (F2, all data).Data collection: SMART (Bruker, 2003); cell

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. A crystal (approximate dimensions 1/4 x 0.12 x 0.04 mm3) was placed onto the tip of a 0.1 mm diameter glass capillary and mounted on a CCD area detector diffractometer for a data collection at 173 (2) K (SMART, Bruker, 2003). A preliminary set of cell constants was calculated from reflections harvested from three sets of 20 frames. These initial sets of frames were oriented such that orthogonal wedges of reciprocal space were surveyed. This produced initial orientation matrices determined from 48 reflections. The data collection was carried out using Mo Kα radiation (graphite monochromator) with a frame time of 8 s and a detector distance of 4.8 cm. A randomly oriented region of reciprocal space was surveyed to the extent of one sphere and to a resolution of 0.77 Å. Four major sections of frames were collected with 0.30° steps in ω at four different ϕ settings and a detector position of -28° in 2θ. The intensity data were corrected for absorption and decay (SADABS, Bruker, 2003). Final cell constants were calculated from 2659 strong reflections from the actual data collection after integration (SAINT, Bruker, 2003). 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 chemistry of half-sandwich molybdenum and tungsten chlorostannyl complexes is undergoing a revival since their discovery roughly forty years ago (Braunschweig et al., 2009). Chlorostannyl ligands permit functionalization at tin in heterobimetallic complexes (Braunschweig et al., 2007). The design of hypervalent tin ligands via intramolecular coordination of cyclopentadienyl-bound tethered donor groups is facilitated by chlorostannyl ligand Lewis acidity (Tang et al., 2005).
The complexes W(SnBu2Cl)(CO)3(η5-Cp) (2) and W(SnMe2Cl)(CO)3(η5-Cp*) (3) were structurally characterized by Braunschweig et al. (2007). The title complex 1 is the first crystallographically characterized substance of general formula M(SnAr2X)(CO)3(η5-Cp).
The Mo—Sn bond length in 1 is slightly shorter (Table 1) than the W—Sn distances found in 2 (2.7959 (5) Å) and 3 (2.7866 (3) Å), respectively. The steric impact of the SnPh3 ligand relative to SnPh2Cl is minimal on the basis of Mo—Sn bond lengths; this separation is 2.8152 (3) Å in Mo(SnPh3)(CO)3(η5-C5H4CH2CH2NMe2) (4) (Fischer et al., 2005). The geometric parameters of 1-4 satisfy the requirements for four-legged piano-stool structures (Kubácek et al., 1982).
The tetrahedral coordination geometry of the tin atoms in 1-3 are distorted more significantly than that of 4. In 4, the diagnostic six angles about tin range from 105.60 (9)° to 116.15 (6)°, while the corresponding angles in 1 range from 100.30 (11)° to 120.34 (11)°. In 1-3 the M—Sn—C angles are widened whereas the C—Sn—Cl angles are more acute in comparison to the ideal tetrahedral angle. The angles about the Sn atoms of 1 and 3 are very similar as the phenyl and methyl substituents, respectively, attempt to minimize steric hinderance with the M(CO)3(Cp) fragment. The C(13)—Sn(1)—Mo (116.32 (10)°) and C(19)—Sn(1)—Mo (120.34 (11)°) angles in 1 are similar to the corresponding angles found in 3 (118.56 (11), 118.31 (12)°). The widening of these angles is accommodated by compression of C—Sn—Cl angles. These angles in 1 (C(13)—Sn(1)—Cl(1), 100.30 (11)°; C(19)—Sn(1)—Cl(1), 101.25 (11)°) are similar to the corresponding angles found in 3 (99.75 (12), 100.48 (13)°).
