Preparation and X-ray Structures of<i>trans</i>-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.
对新制备的标题分子进行的一系列 X 射线分析表明,反式二氢菲罗啉二醇晶体中通常存在一维棒状结构。从超分子手性的角度来看,这种结构非常有趣,因为具有相同螺旋感的同手性二元醇分子通过一对 N-H-O 氢键以头对尾的方式连接在一起。
