61“…The title compound, C(11)H(11)N(3), was synthesized as part of our research into functionalized pyrimidines. It crystallizes with two independent molecules in the asymmetric unit that differ only in the twist between the two aromatic rings; the torsion angles between the rings are 29.9 (2) and 45.1 (2)°. …”
