Hydrogen bonds (blue dotted lines) involving the p-tert-butylcalix[4]arene anion, the methanol molecule included in the cavity, and the [Li(CH3OH)4]+ complex belonging to the asymmetric unit. The centroid of aromatic the ring, Cg1, is represented as a blue sphere. The H atoms of the calixarene host have been omitted for clarity. |
