  Concomitant polymorphism: Crystallising dichloro-bis(2,4-lutidine)-zinc as both chiral and racemic phases

  摘要：

  The crystallisation of dichloro-bis(2,4-lutidine)-zinc from various solvents (e.g. ethanol, THF and 2,4-lutidine) has been investigated and two phases were isolated. The structures of both phases were determined by single crystal X-ray diffraction and both types of crystals were found to be composed of conformationally chiral molecules. One phase (alpha-1) is racemic and crystallises in space group P2(1)/c, while the other phase (beta-1) crystallises in the enantiomorphous space group P4(1)2(1)2 with a low Flack parameter. In a few cases the chiral and racemic phases crystallised concomitantly; this phenomenon is rare and can be useful in the development of tools for the prediction of crystal structures.
