Not only water‐soluble, but also stable from pH 1 to 13 is the first compound of the new class of ligands of tris(pyrazolyl)methanesulfonate ( 1 ). The introduction of the sulfonic acid moiety is responsible for this unusual stability. Thus the reported ligand is probably the better alternative to the sensitive tris(pyrazolyl)borates when it comes to tridentate nitrogen‐donating ligands as enzyme models. R=H, t Bu.
