5,12-Dimethyl-3,10-diphenyl-1,3,4,8,10,11-hexaazatetracyclo[6.6.1.0(2,6).0(9,13)]pentadeca-2(6),4,9,(13),11-tetraene,a new Tröger's base analogue.
The synthesis of the title Tröger's base analogue, C(23)H(22)N(6), was undertaken in order to study the influence of a methyl substituent on the structure. Minor differences were found in the bond lengths of the title structure in comparison with the values for free pyrazole and for the first pyrazolic Tröger's base reported in the literature. There are two molecules of opposite chirality in the asymmetric unit and the packing in the lattice is characterized by a non-crystallographic n-glide plane relating these molecules.
