In the title compounds, C11H18N2, (II), and C13H20N2O, (III), the pyrrolidine rings have twist conformations. Compound (II) crystallizes with two independent molecules (AandB) in the asymmetric unit. The mean planes of the pyrrole and pyrrolidine rings are inclined to one another by 89.99 (11) and 89.35 (10)° in moleculesAandB, respectively. In (III), the amide derivative of (II), the same dihedral angle is much smaller, at only 13.42 (10)°. In the crystal structure of (II), the individual molecules are linkedviaN—H...N hydrogen bonds to form inversion dimers, each with anR22(12) graph-set motif. In the crystal structure of (III), the molecules are linkedviaN—H...O hydrogen bonds to form inversion dimers with anR22(16) graph-set motif.
在标题化合物 C11H18N2(II)和 C13H20N2O(III)中,吡咯烷环呈扭转构象。化合物(II)的结晶在不对称单元中有两个独立的分子(A 和 B)。在分子 A 和分子 B 中,吡咯环和吡咯烷环的平均平面分别相互倾斜 89.99 (11) 和 89.35 (10)°。在(II)的酰胺衍生物(III)中,同样的二面角要小得多,只有 13.42 (10)°。在(II)的晶体结构中,各个分子通过 N-H...N 氢键连接形成反转二聚体,每个二聚体都有一个 R22(12) 图集图案。在(III)的晶体结构中,各分子通过 N-H...O氢键相连,形成反转二聚体,每个反转二聚体都有一个 R22(16) 图集图案。
