This basic thought based on 2 crystals dates back to the times to A.Compton etc. Ito, Yoshiaki Tochio, Tatsunori Fukushima, SeiĪ 4- crystal X-ray spectrometer was designed based on a 2- crystal X-ray spectrometer to be able to perform the absolute measurement of Bragg angle. On the evaluation of the absolute photon energy of Cu Kα, β lines using 4- crystal X -ray spectrometer The resolution of rac-2 by entrainment procedure was successfully realized. Some stabilizing and destabilizing interactions involving the ortho-substituents were revealed. The interplay of the supramolecular crystal organization chirality sense and the single molecule absolute configuration was demonstrated. Two different types of crystal packing were evaluated for these very much alike compounds. The molecular structures and crystal packing details for halogen derivatives were compared with the same characteristics for ortho-OCH 3 and ortho-CH 3 analogues. Three conglomerate-forming ortho-Hal (Hal = Cl, Br, I) substituted phenyl glycerol ethers 1- 3 were investigated by single- crystal X-ray analysis, and the absolute configuration for all substances was established. Absolute configuration and crystal packing chirality for three conglomerate-forming ortho-halogen substituted phenyl glycerol ethersīredikhin, Alexander A.
