(E)-2-[(Pyren-1-yl-imino)-meth-yl]quinolin-8-ol

摘要

In the title compound, C26H16N2O, the pyrene ring system (r.m.s. deviation = 0.021??) is inclined to the planar quinoline ring system (r.m.s. deviation = 0.017??) by 30.62?(5)°, and the conformation about the bridging N=C bond is?E. There is an intra-molecular O—H?N hydrogen bond with an?S(5) ring motif present. In the crystal, mol-ecules are linked by pairs of C—H?O hydrogen bonds, forming inversion dimers with an?R22(14) ring motif, flanked by two?R21(7) ring motifs. The dimers stack along the?b?axis with slipped parallel?π–π?inter-actions involving neighbouring mol-ecules; the shortest?π–π?inter-action involves aromatic rings of the quinoline ring system [inter-centroid distance = 3.6267?(11)??].
