The Kläui ligand is the anion −. The ligand, popularized by Wolfgang Kläui, binds metals and metalloids via a facial O3 donor set. Related tridentate anionic ligands include trispyrazolylborate and cyclopentadienyl anions.〔Wolfgang Kläui, N. Mocigemba, A. Weber-Schuster, R. Bell, W. Frank, D. Mootz, W. Poll, and H. Wunderlich "(): A Novel Organometallic Tris-phosphonic Acid that Dissolves Glass to Form a Six-Coordinate Silicon Complex" Chemistry – European Journal 2002, Volume 8, pages 2335–2340. 〕 : The ligand is derived from the cationic complex of trimethylphosphite 2+ via an Arbuzov reaction.〔W. Kläui�, P. C. Kunz "Sodium (η5-Cyclopentadienyl)tris(dimethylphosphito-P)cobalt(III), Na()" Inorg. Synth., 2010 vol. 35, pp. 125–128. 〕 Using other phosphites and other cyclopentadienyl ligands, a large variety of derivatives are possible. The parent acid H is highly soluble in water (270 g/100 mL). Its p''K''a is about 2. Many complexes have been described, including bis(chelate) complexes of the type 3">)−.
