Preparation and X-ray structures of trans-5,6-diaryl-5,6-dihydro-1,10- phenanthroline-5,6-diols: Formation of supramolecular rod by hydrogen bonds

A series of X-ray analyses on the newly prepared title molecules have revealed that the one-dimensional rod-like structures are commonly present in the crystals of trans-dihydrophenanthrolinediols. The architecture is of interest from the viewpoint of supramolecular chirality because homochiral diol molecules with the same sense of helicity are connected in a head-to-tail fashion by a pair of N···H-O hydrogen bonds.
