Acta Crystallogr C. 2000 Dec;56(Pt 12):1484-6. doi: 10.1107/s0108270100012464.

Abstract

The carboxy group of 2-methyl-N-[(2-nitrophenyl)sulfonyl]alanine, C(10)H(12)N(2)O(6)S, forms centrosymmetric hydrogen-bonded dimers with an O.O distance of 2.629 (2) A and an intramolecular N-H. O(nitro) hydrogen bond N.O distance of 2.823 (2) A. 1-[(2-Nitrophenyl)sulfonylamino]cyclohexanecarboxylic acid, C(13)H(16)N(2)O(6)S, has Z' = 2 and forms similar interactions.
