In the title compound, [Yb(C24H40BN6)2]·C7H8, the Yb atom is coordinated by two tris(3-tert-butyl-5-methylpyrazol-1-yl)hydridoborate [TptBu,Me] ligands. One ligand binds in the κ3 mode, throuh three N atoms of the pyrazolyl rings, the other ligand coordinates through two N atoms of the pyrazolyl rings and the H atom attached to the central B via an agostic-type interaction through the B—H group of the second TptBu,Me ligand, giving an overall distorted octahedral geometry. One of the tert-butyl groups is disordered over two sites, with occupancies of 0.65 and 0.35.

X-ray quality crystals of the titled compound were obtained via ligand redistribution while attempting to grow crystals of (TptBu,Me)Yb(BH4) from a dilute toluene solution cooled to 233 K over several days.
H atom H2B (attached to B atom B2) was allowed to freely refine; the remaining H atoms were generated in idealized positions (according to the sp2 or sp3 geometries of their parent C or B atoms), and then refined using a riding model with fixed C—H and B—H distances (C—H = 0.95–1.00 Å, B1—H1B = 1.00 Å) and with Uiso(H) = 1.2Ueq(C,B). One of the t-butyl groups is disordered over two sites with initially refined occupancies which were finally fixed at 0.65 and 0.35.

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 synthesis, solution structure and spectroscopic characterization of the title compound was reported by Zhang et al. (1995) along with the samarium analogue whose structure was reported then. The structure of the ytterbium analogue is similar to that reported for the samarium compound featuring a distorted six coordinate octahedral geometry formed by five N atoms of two TptBu,Me ligands and additional agostic B—H interaction from the B—H group of one TptBu,Me ligand. The axial sites are occupied by N32 and H2B. The distortion from ideal geometry is obvious from the deviation of the interatomic angles and distances from the idealized values. The intraligand equatorial bonds to the axial N32 are approximately 90° (87.15 (8)° and 93.28 (8)° to N12 and N22, respectively) whereas the corresponding angles to the inter-ligand equatorial N atoms are greater than 90° (97.77 (8)° and 108.92 (8)°, respectively). The distortion from the ideal geometry is also reflected in the non-lineal axial angle of 153.8 (9)°, which is comparable to the value of 152° observed in the samarium analogue. The presence of the B—H agostic interaction is evident in the short Yb—B2 interatomic distance of 3.002 (3) Å, compared to the much longer Yb—B1 separation of 3.310 (3) Å in the unperturbed ligand. Further, the average Yb—N bond distance in the κ3 ligand is shorter than that in the formally κ2 ligand, 2.52 (2) Å and 2.59 (4) Å, respectively.
