Abstract:
The molecules of the title compound, C(26)H(25)N(3)OS, which was prepared by means of an acid-catalysed cyclocondensation reaction between a 6-aminopyrimidinone and 2,6-dibenzylidenecyclohexanone, exhibit a polarized electronic structure, namely (9E)-9-benzylidene-3-methyl-2-methylsulfanyl-5-phenyl-3,5,6,7,8,9-hexahydropyrimido[4,5-b]quinolin-10-ium-4-olate, involving charge separation in the vinylogous amide portion. Four hydrogen bonds, two each of the C-H...O and C-H...pi(arene) types, link the molecules into bilayers comprising inversion-related pairs of sheets, each containing a single type of R(4)(3)(36) ring.
