Abstract

The N-methyl group of the donor is nearly eclipsed with respect to one of the nitro groups of the neighboring acceptor in a column, whereas the N-isopropyl, N-butyl and N-isobutyl groups are in anti positions with respect to one of the nitro groups of the neighboring acceptor in compounds (II)-(IV). In compounds (I)-(IV), the 3,5-dinitrobenzoic acid molecules form a dimeric structure with cyclic hydrogen bonds. The acid proton has two possible positions with site-occupation factors of 50%. They were located from difference syntheses and refined isotropically.
