CCL:2-indanone/crystal structure?



Hello,
 in the last weeks I spend a lot of time for searching literature about
 the
 crystal structure of 2-indanone [CAS: 615-13-4], but I did not find an
 answer. So: Does anybody know something about the CRYSTAL STRUCTURE of
 this small and nice molecule (parameters, space group, exp. and
 theoretical data,...) ?
 Thank you very much.
 Best regards
 Tiziano
