biostudies-literatureUnknown68(Pt 11)Molokoane PPThe title compound, C(10)H(15)NO(2), crystallized with three mol-ecules in the asymmetric unit. These three mol-ecules are quite similar except for slight differences in the torsion angles of the substituents on the ring. The isopropyl C-C-N-C torsion angles (towards the carbon next to the ethyl bound carbon), for example, are -150.63?(11), -126.77?(13) and -138.76?(11)° for mol-ecules A, B and C, respectively, and the C-C-C-N torsion angles involving the ethyl C atoms are 102.90?(13), 87.81?(14) and 86.47?(13)°. The main difference between the three mol-ecules lies in the way they are arranged in the solid-state structure. All three mol-ecules form dimers that are connected through strong O-H?O hydrogen bonds with R(2) (2)(10) graph-set motifs. The symmetry of the dimers formed does however differ between mol-ecules. Mol-ecules B connect with each other to form inversion dimers. Mol-ecules A and C, on the other hand, form dimers with local twofold symmetry, but the two mol-ecules are crystallographically distinct. The B and C molecules are linked to themselves and to each other via C-H?O hydrogen bonds. This results in the formation of a three-dimensional network structure.Acta crystallographica.
