Potassium trispyrazolylborate, commonly abbreviated KTp, is the potassium salt with the formula . This salt is the source of the trispyrazolylborate ligand.
KTp is a white crystalline solid that is soluble in polar solvents, alcohols, and water. The synthesis of KTp involves potassium borohydride and pyrazole without a solvent.
The tris(pyrazolyl)borate forms octahedral coordination compounds with the formula M[Tp]2 with first-row transition metals. KTp also forms 1:1 complexes, for example it can be converted to K[TpMo(CO)3];
When K[TpMo(CO)3] is treated with butyl nitrite it yields the neutral orange complex TpMo(CO)2NO.
