Potassium tris(1-pyrazolyl)borohydride（Cat No.:M074365）, commonly known as KTp, is a scorpionate ligand complex composed of a borohydride core bound to three 1-pyrazolyl groups, with potassium as the counterion. This versatile compound serves as a ligand donor in coordination and organometallic chemistry, where it binds to metal centers via the nitrogen atoms of the pyrazole rings. KTp forms stable, facially coordinating complexes that mimic biological systems, making it valuable in catalysis, bioinorganic modeling, and synthetic transformations. Its steric and electronic properties can be tuned, offering precise control in transition metal complex design and reactivity.
