( E )-2,4-Diamino-5-{7-[(4-chlorophenyl)diazenyl]-3,3-dimethyl-1-oxo-2,3,4,9-tetrahydro-1 H -xanthen-9-yl}-6-oxo-1,6-dihydropyridine-3-carbonitrile dimethylformamide monosolvate

Abstract: In the title compound, C 27 H 23 ClN 6 O 3 ·C 3 H 7 NO, much of the molecule is approximately planar, excluding the pyridinic ring, which is almost perpendicular to this plane, and the sp 3 atoms of the modified xanthene system. The diazene group is E -configured. In the extended structure, two hydrogen bonds of the type N—H...O and one N—H...Cl combine to form a layer structure parallel to (111). The solvent is severely disordered and this necessitated the use of SQUEEZE for a reliable refinement.
