The crystal and molecular structure of the title complex was determined by X-ray method. The absolute configuration of the host (+)-2,2′-dihydroxy-1,1′-binaphthyl (1) was determined to be R and the guest (−)-(ethyl m-tolyl selenoxide) (2) to be S. Two Se–C and one S-O bond lengths are 1.926(7), 1.970(8), and 1.677(5) Å, respectively, and the arrangement around Se atom is roughly tetrahedral. There are O(guest)···HO(host)OH···O(guest) hydrogen bonds between the host and the guest molecules.
