摘要

In the title mol-ecule [systematic name: 10-(prop-2-yn-1-yl)dipyrido[3,4-b:3′,4′-e][1,4]thia-zine], C13H9N3S, the dihedral angle between the two pyridine rings is 146.33?(7)° and the angle between two halves of the thia-zine ring is 138.84?(8)°, resulting in a butterfly shape for the tricyclic system. The central thia-zine ring adopts a boat conformation, with the 2-propynyl substituent at the thia-zine N atom located in a pseudo-equatorial position and oriented to the concave side of the diaza-phenothia-zine system. In the crystal, mol-ecules are arranged via π–π inter-actions between the pyridine rings [centroid–centroid distances = 3.838?(1) and 3.845?(1)??] into stacks extending along [001]. There are C—H?C and C—H?N inter-actions between mol-ecules of neighbouring stacks.
