SOME GOLD(III) DERIVATIVES OF PYRAZOLES

Various gold(III) derivatives of pyrazoles, pzH, were obtained and characterized. Besides the salt [3,5-Ph2pzH2][AuCl4], they included adducts, AuCl3·pzH, μ-pyrazolato-N,N′-derivatives, [Cl2Au(pz)]n (such as: n = 2 and pz = 3,5-diphenyl-4-chloropyrazolato), and one derivative containing both a neutral pyrazole and a pyrazolato ligand, Cl2Au(3,5-Ph2pz-N)(3,5-Ph2pzH).
