The title compound, C(16)H(13)N(3), isolated from Justicia secunda (Acanthaceae), comprises two molecules (which differ slightly in conformation) in the asymmetric unit of space group P-1. Intermolecular N(amino)-H.N(pyrm) interactions (N(pyrm) is a pyrimidine ring N atom) involve only one of the two donor amino H atoms and pyrimidine N atoms per molecule, forming dimeric units via R(2)(2)(8) rings, with N.N distances of 3.058 (2) and 3.106 (3) A, and N-H.N angles of 172.7 (18) and 175.8 (17) degrees. The dimers are linked by C-H.pi(arene) contacts, with an H.centroid distance of 2.77 A and a C-H.centroid angle of 141 degrees. |
