9-(2-Hy­droxy­benzyl­idene)amino-11-(2-hy­droxy­phen­yl)-1013-diphenyl-8-oxa-12-azoniatricyclo­7.3.1.027trideca-2(7)35-triene acetate ethanol disolvate

摘要

The title compound, C36H31N2O3 ⁺,C2H3O2 ⁻·2C2H5OH, the product of a domino condensation of dibenzyl ketone with salicylic aldehyde and ammonium acetate, crystallized as the ethanol disolvate. The cation of the salt comprises a fused tricyclic system containing three six-membered rings (piperidine, dihydro-2H-pyran and benzene). The piperidine ring has the usual chair conformation, while the dihydro­pyran ring adopts a slightly distorted sofa conformation. In the crystal, there are six (one intra- and five inter­molecular) independent hydrogen-bonding inter­actions: the inter­molecular hydrogen bonds link the cations and anions and ethanol solvent mol­ecules into ribbons along [001]. The ribbons are stacked along the a axis.
