N-(n-Dec-yl)-4-nitro-aniline

Abstract

N-(n-Dec-yl)-4-nitro-aniline, C(16)H(26)N(2)O(2), crystallizes with two essentially planar mol-ecules in the asymmetric unit. The decyl chains are fully extended in an anti conformation. The mol-ecules pack in planar layers, within which mol-ecules are linked into chains by two approximately linear N-H⋯O hydrogen bonds between the amine N atom and one O atom of the nitro group of an adjacent mol-ecule. These mol-ecular chains propagate via inter-leaving of the decyl chains to form the two dimensional sheets. The sheets are associated exclusively via non-bonded contacts. The structure has features in common with those of other N-alkyl-4-nitro-anilines, but also subtle differences in packing.
