achiral molecules and chiral crystals

sylla - 22-10-2007 at 07:28

Hi everyone,

I'm currently investigating the properties of achiral molecules that crystallize as chiral crystals. The problem is that it has been so far very hard to establish a list of such compounds...

I have started with sodium chlorate and benzil (1,2-diphenylethanedione) and read about sodium bromate having similar properties (I still have to confirm that one). After a few weeks of research I could hardly find anything new.

So I decided to ask the fellow scientists of scimad :cool: By any chance, does anybody have heard about compound (organic or inorganic) having such properties ? Thx

If you have access to Cambridge Structural Database you may do a search for compounds that crystallize in the chiral space groups. There are not an enormous amount of conglomerates reported in a litteratue (the current estimate is that 5-10% of the organometallics/organics can behave this way), but quite enough to keep you busy for a very long while. There have also been some pretty good review articles published on the matter in the past few years although I don't have my references handy at the moment (but search for conglomerates in SciFinder and you will find them in a matter of minutes).

EDIT: Found a few references in my paper stack. Linked below:
