• Poly(pyrazolyl)borate degradation
• Pyrazaboles
• Ruthenium(II)
• Pnicogen bond

The reaction of [Ru(H)(Cl)(CO)(PPh3)(3)] (1) with KTp* (KTp* = Potassium tris(3,5-dimethylpyrazolyl)borate) in a refluxing toluene yields a mixtures of [RuTp*(H)(CO)(PPh3)] (2), [Ru(H)(Cl)(pz*H)(CO)(PPh3)(2)] (3), and [H(pz*)B(mu-pz*)(2)B(pz*)H] (4) (pz*H = 3,5-dimethylpyrazole). The products (3) and (4) were obtained by the degradation of the scorpionate ligand, Tp*. These complexes were characterised by IR, H-1 NMR, UV, X-ray crystallography and DFT calculations.
