The title compound, C38H30N4, a potentially mono- and bidentate ligand, does not seem to form palladium complexes similar to other poly(pyrazol-1-ylmethyl)benzenes due to the large steric size of the phenyl substituents on the pyrazole rings. The pyrazole rings have a 21.09 (5)° angle between their mean planes and exhibit a trans-like geometry in which the in-plane lone pairs of electrons on the 2-N nitrogen atoms point in opposite directions.

For information on the related compounds 1,2-bis[(3-(2,2′-bipyridin-6-yl)pyrazol-1-yl)methyl]benzene and 2,3-bis[(3-(2-pyridyl)pyrazol-1-yl)methyl]naphthalene, see: Al-Rasbi et al. (2007 ▶); Paul et al. (2003 ▶). Geometrical parameters were checked with Mogul (Bruno et al., 2002 ▶).
