Crystal structure of 2-methylamino-4-(6-methyl-4-oxo-4H-chromen-3-yl)-3-nitropyrano[3,2-c]chromen-5(4H)-one with an unknown solvate
In the title compound, C(23)H(16)N(2)O(7), the mean planes of the two chromene units (r.m.s. deviations = 0.031 and 0.064 Å) are almost normal to one another with a dihedral angle of 85.59 (6)°. The central six-membered pyran ring has a distorted envelope conformation, with the methine C atom at the...
