In the year that the CSD hit one million structures we wanted to highlight and thank some of the most prolific contributors to the database. The 9th person in this series is Allan H. White who is currently 2nd in our annual CSD author statistics!

About Allan H. White

Allan H. White is an expert in the field of crystallography and structural chemistry.  He has been an academic staff member of the Chemistry Department and the Crystallography Centre at The University of Western Australia since 1966, becoming Emeritus Professor in 2010, and having been Professor of Chemistry and Crystallography from 1999 to 2007.  He has many academic qualifications and awards, including receiving the Chancellor’s Medal from the University of Western Australia in 2009.(1) 


A.H.White and the CSD

Allan is currently 2nd in our annual list of most prolific authors in the CSD with over 5,700 entries in the CSD.  Allan has submitted entries to the CSD almost every year since 1970.  His busiest year to date was 2005, when he submitted 359 entries.  A graph showing the growth of Allan’s entries in the CSD per year is shown below.

Allan has published structures in over 75 different journals with over 1,385 unique co-authors.  81 % of his entries have been co-authored with B.W.Skelton.  His structures are diverse; they include 78 different element types, a massive 516,251 atomic coordinates and cover 107 difference space groups.  One of his largest structures in terms of the number of atomic coordinates (1,075) is CSD Entry: JIYPUD which was published in Organometallics in 2008.

Allan has many more entries in the metal-organic (4,321, 76 %) than the organic (1,400, 24 %) disciplines. His structures have an average R-factor of 4.84, lower than the average R-factor of the entire CSD and 28% of his structures have modelled disorder.

We have enjoyed browsing through Allan’s entries in the CSD. Each entry is valuable individually and collectively they contain a wealth of data that can be used by scientists worldwide. Thank you, Allan H. White, for all your hard work and for all your amazing structures!

Get involved

This is the 9th and penultimate 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 you can tweet us @ccdc_cambridge and use the hashtag
