Abstract
Molecules of the title compound, C28H27ClN4O4.C2H6O, form a C(6) chain via an N-H . . .O hydrogen bond along the c axis by the operation of a c-glide plane, with N . . .O = 2.761 (3) Angstrom and N-H . . .O = 165 degrees. The molecules are further linked by a weak C-H . . .O interaction, with C . . .O = 3.344 (4) Angstrom and C-H . . .O = 150 degrees. Pendant hydrogen-bond ed ethanol solvent molecules are attached to the chains by O-H . . .N hydro gen bonds, with O . . .N = 2.904 (3) Angstrom and O-H . . .N = 175 degrees.
