On the structure of 9-amino-2,7-di-tert-butylacridine

Abstract

The crystal structure of 9-amino-2,7-di-tert-butylacridine hydrochloride monohydrate, C_(21)H_(27)N_2^+.Cl^-.H_2O, has been described in space group P3_1 [trigonal, a = 11.086 (2), c = 14.367 (4) Å, Z = 3; McKenna, Agbandje & Neidle (1992). Acta Cryst. C48, 188-190]. It is properly described in space group P3_121. Further refinement in P3_121, based on the original F values, leads to an improved R (0.049 vs 0.067) and to a revised position for the Cl^- ion.
