Open publisher page 15 citations

Abstract

This paper forms part VI in the series of the crystal structures of hydrophobic amino acids. A low-temperature form (120 K) of dl-norleucine (2-aminohexanoic acid, C6H13NO2), has been solved and refined in the space group C2/c. Molecular packing and cell parameters correlate very well with those proposed for the β-form of dl-norleucine as deduced by Mathieson [Acta Cryst. (1953), 6, 399–403]. Estimated standard deviations betweeen heavy atoms are 0.001–0.002 Å.
