Abstract
Metal thiocyanates are some of the earliest reported molecular framework materials and adopta diverse range of structures. This review describes the structures, properties and syntheses ofthe known binary and ternary thiocyanates. It provides a categorization of their diverse structures,and connects them to the structures of atomic inorganic materials. In addition to this description ofcharacterized binary and ternary thiocyanates, the review summarizes the state of knowledge forall other binary metal thiocyanates. The review concludes by highlighting opportunities for futurematerials development.
