description Crystal structure determination of doxorubicin nitrate, (DoxH)NO(3), systematic name (7S,9S)-7-{[(2R,4S,5S,6S)-4-azaniumyl-5-hy­droxy-6-methyl­oxan-2-yl]­oxy}-6,9,11-trihy­droxy-9-(2-hy­droxy­acet­yl)-4-meth­oxy-8,10-di­hydro-7H-tetra­cen-5,12-dione nitrate, shows two formula units present in the asymmetric unit. In the crystal lattice, hydrogen-bonded pairs of (DoxH(+)) cations and segregation of the aglycone and sugar moieties are observed. Inspection of mol­ecular overlays reveals that the conformation of (DoxH)NO(3) resembles that of DNA-inter­calated, but not of protein-docked (DoxH)(+). The structure was refined as a two-component twin.
