Abstract

In the title compound, [Yb(C₂₄H₄₀BN₆)₂]·C₇H₈, the Yb atom is coordinated by two tris(3-tert-butyl-5-methylpyrazol-1-yl)hydridoborate [Tp^tBu,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 Tp^tBu,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.
