Pearson's Crystal Data
Crystal Structure Database for Inorganic Compounds
Pearson's Crystal Data is a crystallographic database,
edited by Pierre Villars and Karin Cenzual. It is published by
ASM International, Materials Park, Ohio, USA. The "PCD" (as it is typically abbreviated) contains crystal
structures of a large variety of inorganic materials and compounds. The
collaboration between ASM International and
Material Phases Data System, Vitznau, Switzerland (MPDS), aims to
create and maintain the world's largest critically evaluated "Non-organic
database".
The current release 2009/10 of the "PCD" contains more than 180,000 structural data sets (including atom coordinates and displacement
parameters, when determined) for more than 100,000 different phases, roughly 14,000 experimental powder diffraction patterns and about 167,000 calculated
patterns. It achieves an ICSD coverage of
more than 95%.
The database comes with an innovative retrieval software for Windows PCs developed by Crystal Impact. It offers a large variety of
new elaborate new features which make retrieval of the desired information extremely easy and comfortable.
