chelate
This term is primarily restricted to chemistry and medicine, describing a specific type of coordination where a ligand grips a metal ion like a claw. It carries a technical, clinical connotation, often associated with detoxification or the stabilization of minerals within a biological system.
As a noun, the word refers to the resulting complex. While it follows standard countability rules, it is frequently used in technical literature to describe a specific chemical species or a class of compounds, often appearing in the context of "chelating agents" which are the molecules that perform the binding action.
