Chiral guest in a chiral framework: X-ray diffraction study

详细

The inclusion compound of zinc lactate terephthalate with R-butan-2-ol, [Zn₂(R-Bu^sOH) (bdc)(S-lac)]•(R-Bu^sOH) (Bu^sOH is butan-2-ol, H₂bdc is terephthalic acid, S-H₂lac is lactic acid), was prepared by soaking crystals of [Zn₂(dmf)(bdc)(S-lac)]•DMF in pure R-butan-2-ol. The positions of chiral alcohol molecules in voids of the chiral framework and the host–guest contacts were determined by X-ray diffraction. These data provide an explanation for the origin of chiral discrimination of zinc lactate terephthalate toward the R-isomer of butan-2-ol.
