RESUMO
In the title compounds, C32H25ClN2O4 (I) and C33H28N2O5 (II), the six-membered pyran and piperidine rings adopt envelope and chair conformations, respectively. The five-membered pyrrolidine rings adopt twist conformations. Compound (II) crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In all three mol-ecules there is a C-Hâ¯O intra-molecular hydrogen bond present enclosing an S(7) ring motif. In (I), both oxygen atoms of the nitro group are disordered, while in (II) the meth-oxy-benzene group is disordered in mol-ecule B. The geometries were regularized by soft restraints. In the crystal of (I), mol-ecules are linked by C-Hâ¯O hydrogen bonds, forming chains along [010]. The chains are linked by C-Hâ¯Cl hydrogen bonds, forming layers parallel to (10). Within the layer there are C-Hâ¯π inter-actions present. In the crystal of (II), the A and B mol-ecules are linked via C-Hâ¯O hydrogen bonds, forming a square four-membered A-B-A-B unit. These units are linked by a number of C-Hâ¯π inter-actions, forming a three-dimensional supra-molecular structure.
RESUMO
The title compound, C35H27ClN4O3, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the pyran and pyridine rings adopt envelope and chair conformations, respectively. The conformation of the pyrrolidine and cyclo-pentene rings differ in the two mol-ecules; twisted and flat, respectively, in mol-ecule A, but envelope and twisted, respectively, in mol-ecule B. In both mol-ecules, there is a C-Hâ¯N intra-molecular hydrogen bond present. In both mol-ecules, the oxygen atoms of the nitro groups are disordered as is the chlorine atom in mol-ecule B. In the crystal, the B mol-ecules are linked by C-Hâ¯O hydrogen bonds, forming -B-B-B- chains along [010], and by C-Hâ¯π inter-actions. The A and B mol-ecules are also linked by a number of C-Hâ¯π inter-actions, resulting in the formation a supra-molecular three-dimensional structure. In mol-ecule A, the nitro group oxygen atoms are disordered over two positions with refined occupancy ratios of the nitro group oxygen atoms O3A and O4A in 0.59â (2):0.41â (2) while in molecule B one of the nitro O atoms is disordered over two positions with a refined occupancy ratio of 0.686â (13):0.314â (13) and the chlorine atoms is disordered over two positions with a refined occupancy ratio of 0.72â (3):0.28â (3).
