Bis[tris(3-tert-butyl-5-methylpyrazol-1-yl)hydridoborato]ytterbium(II) toluene solvate

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...

Description
Summary: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.
