✦ Synopsis

The title compound, C 12 H 9 NSÁC 6 H 3 N 3 O 7 , is a 1:1 adduct of neutral phenothiazine (pz) and picric acid (pa). A weak bifurcated N-HÁ Á Á(O,O) hydrogen bond links the pa and pz species and an intramolecular O-HÁ Á ÁO bond occurs within the pa molecule. The O atoms of one of the pa nitro groups are disordered over two positions of almost equal [0.54 (2): 0.46 (2)] occupancy. The dihedral angle between the pz aromatic ring planes is 11.81 (10) .
