Pearson's Crystal Data
Crystal Structure Database for Inorganic Compounds

Pearson's Crystal Data is a crystallographic database published by ASM International (Materials Park, Ohio, USA), edited by Pierre Villars and Karin Cenzual. It has its roots in the well-known PAULING FILE project and contains crystal structures of a large variety of inorganic materials and compounds. The "PCD" (as it is typically abbreviated) is a collaboration between ASM International and Material Phases Data System, Vitznau, Switzerland (MPDS), aiming to create and maintain the world's largest critically evaluated "Non-organic database".

The current release 2012/13 contains more than 227,000 structural data sets (including atom coordinates and displacement parameters, when determined) for about 133,500 different chemical formulas, roughly 16,000 experimental powder diffraction patterns and about 195,000 calculated patterns (interplanar spacings, intensities, Miller indices). This release achieves nearly full overlap with ICSD entries.

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.
