About CrystG3

CrystG3 is a searchable database of crystal structures and their G3 characteristics. It provides composition-based search, structure properties, atom-site data and interactive CIF visualization in one place.

20838 Crystal structures
73 Chemical elements represented
108785 Non-equivalent atom sites

Funding

The development of CrystG3 is supported by the UMNIK grant program, Grant No. 19796ГУ/2025.
