The molecular structure of the tetrahydrofuran adduct of the first dimeric mono[tris(pyrazolyl)borate] (Tp) lanthanide compound of composition [Yb2(C9H10BN6)2Cl4(C4H8O)2]·C7H8 is reported. The dimeric and centrosymmetric mono-Tp complex features a seven-coordinate Yb atom, bonded to three N atoms of the tridentate ligand, to the O atom of the neutral tetrahydrofuran ligand, and to one terminal as well as to two bridging Cl atoms. Additionally, a disordered toluene solvent molecule, located on an inversion center, is cocrystallized.

Special details top
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. Toluene disorder on inversion center. Fully modeled. H atoms neglected in final
model but included in all intensive calculations. 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. |
