Bis(benzyl­tri­methyl­ammonium) bis­[(4SR,12SR,18RS,26RS)-4,18,26-trihy­droxy-12-oxido-13,17-dioxahepta­cyclo­[14.10.0.0(3,14).0(4,12).0(6,11).0(18,26).0(19,24)]hexa­cosa-1,3(14),6,8,10,15,19,21,23-nona­ene-5,25-dione] sesquihydrate: dimeric structure formation via [O—H—O](−) negative charge-assisted hydrogen bonds (–CAHB) with benzyl­tri­methyl­ammonium counter-ions

The reaction between bis-ninhydrin resorcinol and benzyl­tri­methyl­ammonium fluoride in ethanol has produced the title compound, 2C(10)H(16)N(+)·2C(24)H(13)O(8) (−)·1.5H(2)O, which contains a unique centrosymmetric supra­molecular dimeric entity, where two deprotonated ligands are held together via...
