Comments on Inorganic Chemistry is intended as a vehicle for authoritatively written critical discussions of inorganic chemistry research. We publish focused articles of any length that critique or comment upon new concepts, or which introduce new interpretations or developments of long-standing concepts. “Comments” may contain critical discussions of previously published work, or original research that critiques existing concepts or introduces novel concepts.Through the medium of “comments,” the Editors encourage authors in any area of inorganic chemistry - synthesis, structure, spectroscopy, kinetics and mechanisms, theory - to write about their interests in a manner that is both personal and pedagogical. Comments is an excellent platform for younger inorganic chemists whose research is not yet widely known to describe their work, and add to the spectrum of Comments’ author profiles, which includes many well-established inorganic chemists.
