Experimental Crystal data

R factor = 0.055; wR factor = 0.163; data-to-parameter ratio = 16.0. In the title compound, C10H9N3O, the organic rings linked to the ether O atom make a dihedral angle of 76.8 (1) and the C—O—C angle is widened to 119.07 (15). In the crystal, adjacent molecules are connected by an N—H N hydrogen bond, generating a chain running parallel to the b axis. The crystal is a non-merohedral twin with a ratio of twin components of 0.508 (3):0.492 (3). Related literatur
