Crystal structure of 4-(6-bromo-4-oxo-4H-chromen-3-yl)-2-methylamino-3-nitropyrano[3,2-c]chromen-5(4H)-one chloroform monosolvate

Crystal structure of 4-(6-bromo-4-oxo-4H-chromen-3-yl)-2-methylamino-3-nitropyrano[3,2-c]chromen-5(4H)-one chloroform monosolvate

In the title compound, C22H13BrN2O7·CHCl3, the pyran ring adopts a shallow sofa conformation with the C atom bearing the bromochromene system as the flap [deviation = 0.291 (3) Å]. The dihedral angle between the pyran fused-ring system (all atoms; r.m.s. deviation = 0.032 Å) and the bromochromene ri...
