Abstract
Over the decades, numerous crystal structures of the monolayer-protected clusters (MPCs) have been reported and the number of discoveries is rapidly increasing. Via crystallography, it is possible to construct the atomic structures with atom level precision. This enables computational and theoretical studies, which can shed light to the origin of experimentally observed properties and help discoveries of new materials. However, the reported MPC crystal structures are commonly deposited into large crystallographical databases or dispersed in supplementary information files of the publications, and in order to find all of them one is required go through an immense amount of literature. Hence, it is of interest to establish an editable catalog for the community to keep track of discoveries. The catalog is hosted in Wikipedia and this paper works as an initialization document and a citable source for the catalog.
