Abstract:
The title compound, C(12)H(21)NO(3), crystallizes in two polymorphic forms, viz. the tetragonal form described here and the monoclinic form described previously [Foces-Foces, López-Rodríguez, Pérez, Martín & Pérez-Hernández (2007). Cryst. Growth Des. 7, 905-911]. The differences in the conformations of the hydroxymethyl and methylaminocarbonyl substituents have important consequences in the hydrogen-bond interaction motifs and, therefore, in the packing arrangements. These forms are concomitant polymorphs with melting points differing by 3 K.

Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
