Abstract

Crystallography Physical Sciences Science & Technology
The triazoloquinazoline fused-ring system of the title compound, C10H8N4O3S, is essentially planar (r.m.s. deviation = 0.027 angstrom). In the crystal, adjacent molecules are linked by N-H center dot center dot center dot(Osulfonyl) hydrogen bonds, generating a helical chain running along the b axis.
