1,5-Diphenyl-4,8-bis(3-phenylpyrazol-1-yl)pyrazabole.

The six-membered B2H4 ring of the title compound, C36H30B2N8, adopts a slightly distorted boat conformation, with the terminal B substituents in a trans orientation. One 3-phenylpyrazolyl group is in an equatorial position, whereas the second is in an axial position with respect to the plane defined by the B atoms.
