The asymmetric unit of the title compound, C40H 26C4·-2(CH3)2CO, consists of one molecule of (R,R)-3,3′-bisBINOL [(R,R)-1,1′:3′,3″: l″,1‴-quater-2-naphthol] and two acetone molecules. The central feature of the structure is the pair of unique sets of O-H⋯O⋯H-O hydrogen-bond arrangements between the two hydroxy groups of (R,R)-3,3′-bisBINOL and the O atom of acetone, which fixes the axial chirality of the 3,3′-bond as 5, thus maintaining the helical structure of the bisBINOL in the M form.
