Organic and organometallic compounds
available in the Aldrich catalog,
and absent in CSD.

---

• Many of these compounds are obviously candidates for either a single crystal structure determination or a SDPD (Structure Determination by Powder Diffractometry) if the crystals are too small (of course, bad crystallinity may preclude any study, or hygroscopicity may lead to a more difficult job, low melting point, etc).
• Compounds below are obtained from the comparison of the French 2000-2001 Aldrich catalog and  the CSD (thanks to the CCDC staff for providing the data : 214223 unique chemical compound out of 257161 entries - CSD version 5.23 - April 2002).
• Waiting for obtaining the digitalized full molecular formula index of Aldrich solid compounds, the search is performed one by one, at random, and the list is incomplete, so far ;-). More to come soon, day after day (?).
• See also the list of > 300 minerals with unknwon crystal structure.
