A tris(pyrazolyl)borate rhodium phosphite complex that undergoes an Arbusov-like rearrangement

Tp'Rh[P(OMe)₃](Me)H, loses methane in pentane solution containing CH₂F₂ to give the scorpionate complex bis([mu]-dimethyl phosphito)-[kappa]²P:O;[kappa]²O:P-bis{methyl[tris(3,5-dimethyl-1H-pyrazol-1-yl-[kappa]N²)bor­ato]rhodium(III)}, [Rh₂(CH₃)₂(C₂H₆O₃P)₂(C₁₅H₂₂BN₆)₂], in which the phosphine O-Me bond is cleaved. The product is dimeric and resembles the Arbusov-type rearrangement product known to form from trimethyl phosphite.

Special details

Experimental. A crystal was placed on the tip of a 0.1 mm diameter glass capillary tube or fiber and mounted on a Bruker SMART APEXII CCD Platform diffractometer for a data collection at 100.0 (5) K. A preliminary set of cell constants and an orientation matrix were calculated from reflections harvested from three orthogonal wedges of reciprocal space. The full data collection was carried out using Mo Kα radiation (graphite monochromator), with a frame time of 60 s and a detector distance of 4.01 cm. A randomly oriented region of reciprocal space was surveyed; six major sections of frames were collected with 0.50° steps in ω at six different ϕ settings and a detector position of -38° in 2θ. The intensity data were corrected for absorption. Final cell constants were calculated from the xyz centroids of 4044 strong reflections from the actual data collection after integration. The space group P1 was determined based on intensity statistics. A direct methods solution was calculated which provided most non-H atoms from the E map. Full-matrix least-squares/difference Fourier cycles were performed which located the remaining non-H atoms. All non-H atoms were refined with anisotropic displacement parameters. All H atoms were placed in ideal positions and refined as riding atoms with relative isotropic displacement parameters.

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. Highly disordered solvent was located in channels parallel to the b axis. Reflection contributions from this solvent were removed using program PLATON, function SQUEEZE (Spek, 2003), which determined there to be 96 electrons in 250 ų removed per unit cell. Since the exact identity and amount of solvent could not be determined, no solvent was included in the atom list or molecular formula. (One set of residual peaks did appear to be n-pentane, disordered over an inversion center. However, this did not define the entire solvent area.) Thus all reported items that derive from the molecular formula (e.g., F(000), density, molecular weight, etc.) are known to be incorrect.

The large residual peak of 4.57 electrons per ų, located 0.74 Šfrom the rhodium atom, may be the result of residual absorption errors.
