CSD Heroes: Frank Fronczek

Our fourth CSD Hero is Frank Fronczek, currently 7th in our annual CSD author statistics

Frank Fronczek is Director of the X-ray Facility at Louisiana State University and a Fellow of the American Crystallographic Association.  He was a postdoc at the University of California at Berkeley after receiving his PhD at Caltech, with Dick Marsh (trained by Linus Pauling) and Bill Schaefer.(1) 

We would like to thank Frank by highlighting some of his key contributions to the CSD.

Frank R. Fronczek and the CSD

Frank is currently 7th in our annual list of most prolific authors in the CSD with over 3,300 entries dating back to 1975. His busiest year was 2015 with a massive 465 submitted entries, 384 of which were published as CSD Communications

Frank is also one of our “CSD Communications Heroes”, having published 1,445 CSD Communications overall.  His 1st CSD Communication was published in 1995, CSD Entry SUCCIN08, https://dx.doi.org/10.5517/cc45q44.  Frank’s 1000th CSD Communication, published in 2015, we have nicknamed “The CSD Man”, CSD Entry: XURZAN, is shown below.

Frank’s structures are diverse and include 67 different element types, a massive 219,474 atomic coordinates, and cover 77 different space groups.  One of his largest structures in terms of the number of atomic coordinates (822) is CSD Entry: MIPYAM,published in Chemistry-A European Journal.

His entries are more in the organic discipline (74%, 2,490 entries) than the metal-organic discipline (26%, 877 entries).  Frank’s structures have an average R-factor of 4.6, below the average R-factor of the entire CSD and 21% of his structures have modelled disorder.

We have enjoyed browsing through Frank’s structures, each structure is valuable individually and collectively they contain a wealth of data that can be used by scientists worldwide. Thank you, Frank, for all your efforts and for all your wonderful structures!

 

Get involved

This is the 4th blog in our series of blog posts featuring the most prolific authors in the CSD which highlight some statistics and structures to celebrate their achievements and thank them for their phenomenal contribution. If you would like to share stories about these crystallographers, some of their fascinating structures or tell us about your heroes of the CSD tweet us @ccdc_cambridge using hashtag #CSDHeroes19
