Bis(4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato-κO)tetra­kis­(methanol-κO)calcium methanol tetra­solvate

In the title compound, [Ca(C₁₉H₁₁F₂O₂)₂(CH₃OH)₄]·4CH₃OH, the Ca²⁺ ion is located on an inversion centre and is hexa­coordinated by two O atoms of two 4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ate ligands and four O atoms of four methanol ligands, forming a CaO₆ polyhedron with a slightly distorted octa­hedral coordination geometry. The Ca—O—C angle between the carboxyl­ate group and the calcium ion is 171.8 (2)°. Two types of inter­molecular hydrogen-bond inter­actions (C=O...H and O—H...O) between the carboxyl­ate ligand, the methanol solvent mol­ecules and the coordinating methanol ligands generate a two-dimensional network parallel to (001).

2-Benzhydryl-6-tert-butyl-4-methyl­phenol

The title compound, C₂₄H₂₆O, was prepared by the reaction between 2-tert-butyl-4-methyl­phenol and diphenyl­methanol in the presence of sulfuric acid. Three benzene rings are attached directly to the central C—H group in a twisted propeller conformation with the local pseudo-C₃ rotational axis coinciding with the C—H bond. There are three short C—H...O contacts in the molecule.
