WebNov 13, 2009 · TPE 1 is an achiral organic compound; however, the single-crystal structure belongs to the chiral space group P2 1 (Hoekstra and Vos 1975).The four phenyl rings are twisted in the same sense relative to the olefinic plane in the crystal lattice. This propeller-like conformation makes TPE 1 chiral, thus the resulting two enantiomeric forms, i.e., P …
