About our speaker

Dr. Dean Johnston has taught General and Inorganic Chemistry at Otterbein University for over 20 years. His research focuses on the synthesis and crystallographic characterization of metal cluster compounds. He received his B.A. in Chemistry from the College of Wooster and his M.S. and Ph.D. from Northwestern University working with Professor Duward Shriver. After a postdoctoral fellowship working with Holden Thorp at UNC-Chapel Hill, he began working at Otterbein. Most recently, in the Fall of 2017, he spent a sabbatical working with the Cambridge Crystallographic Data Centre in the UK and at Rutgers University. 

Presentation Abstract

The Cambridge Structural Database (CSD) is a rich resource containing over 900,000 highly-curated entries on a wide range of organic and organometallic compounds. These data can be "mined" using various tools including the CSD Python Application Programming Interface (API). In one project, we have surveyed the diversity of metal cluster chemistry by tabulating the connectivity and total electron counts of some of the over 20,000 metal cluster structures in the CSD. In a second project, we have looked at the distribution of atomic displacement parameter (temperature factor) data and the possibility of using this information to validate reported data collection temperatures for newly-deposited data. Finally, applications and opportunities for using the CSD to illustrate fundamental chemical concepts will be presented.
