Аннотация
8-(1-([1,1¢-biphenyl]-4-ylmethyl)piperidin-4-yl)-3,4-dihydroquinolin-2(1 H )-one (1) and 8-(4-([1,1¢-biphenyl]-4-ylmethyl)piperazin-1-yl)quinolin-2(1 H )-one (2) are prepared in the crystalline state and studied by X-ray diffraction. The crystal packing drawing of compound (1) indicates that individual molecules are linked by pairs of N-H⋯O hydrogen bonds forming A-A and B-B inversion dimers, with (8) ring motifs. These dimers are stabilized by N-H⋯O hydrogen bonds and linked via C-H⋯O short contact interactions forming a two-dimensional network. In the case of compound (2), there are two independent molecules A and B linked by pairs of N-H⋯O hydrogen bonds forming A-A and B-B inversion dimers, with (8) ring motifs. These dimers are stabilized by N-H⋯O hydrogen bonds and linked via C-H⋯O short contact interactions forming a two-dimensional network.
