The chloroform-solvated uranyl complex of p-tert-butyl­hexa­homo­tri­oxa­calix[3]arene with the chiral counter-ion (S)-(–)-N,α-dimethyl­benzyl­ammonium

In the title compound, (S)-(−)-N,α-dimethyl­benzyl­ammonium dioxo[7,15,23-tri-tert-butyl-3,11,19-trioxatetra­cyclo­[19.3.1.1^5,9.1^13,17]hepta­cosa-1(25),5,7,9(27),13,15,17(26),21,23-nona­ene-25,26,27-triolato]uranate(VI) chloroform solvate, (C₉H₁₄N)[UO₂(C₃₆H₄₅O₆)]·CHCl₃, the uranyl ion is bound to the three phenoxide groups and two of the ether groups of the deprotonated p-tert-butyl­hexa­homo­tri­oxa­calix[3]arene mol­ecule in a cone conformation, giving a mono-anionic complex. The chiral counter-ion, (S)-(−)-N,α-dimethyl­benzyl­ammonium, is included in the cavity and involved in both a hydrogen bond with the uranyl oxo group directed inwards and an N—H...π inter­action with one of the aromatic rings.
