The title compound, C17H12N4, belongs to a group of N-bridgehead purine ana
logue ligands. The nine atoms comprising the triazolopyrimidine core have a
n r.m.s. deviation of 0.023 Angstrom from the mean plane. The two phenyl gr
oups attached to the core form interplanar angles of 27.38 (6) and 55.76(3)
degrees with this core plane.
