Potassium trispyrazolylborate
Potassium trispyrazolylborate, commonly abbreviated KTp, is the potassium salt of the trispyrazolylborate ligand.
KTp is a white crystalline solid which is soluble in polar solvents, alcohols, and water. The synthesis of KTp involves potassium borohydride and pyrazole without a solvent.
The trisborate forms octahedral coordination compounds with the formula M2 with first row transition metals. KTp also forms 1:1 complexes, for example it can be converted to K;
When K is treated with butyl nitrite it yields the neutral orange complex TpMo2NO.
