Crystal structure of a supra-molecular lithium complex of p-tert-butyl-calix[4]arene.

ABSTRACT: Crystals of a supra-molecular lithium complex with a calix[4]arene derivative, namely tetra-methano-llithium 5,11,17,23-tetra-tert-butyl-25,26,27-trihy-droxy-28-oxidocalix[4]arene methanol monosolvate, [Li(CH₃OH)₄](C₄₄H₅₅O₄)·CH₃OH or [Li(CH₃OH)₄]⁺·(calix[4]arene^-)]·CH₃OH (where calix[4]arene^- represents a mono-anion species because of deprotonation of one H atom of the calixarene hy-droxy groups), were obtained from p-tert-butyl-calix[4]arene reacted with LiH in tetra-hydro-furan, followed by recrystallization from methanol. The asymmetric unit comprises one mono-anionic calixarene mol-ecule, one Li⁺ cation coordinated to four m
