چکیده
The Au atom in the C2-symmetric pincer-type title complex, [AuCl(C(19)H(23)N(5))], is in the +3 oxidation state. The ligand is composed of one pyridine unit and two n-butyl-substituted pyrazoles (pyrz). Both pyrazoles are deprotonated, thus forming a neutral compound. To the best of our knowledge, this is the first Au(III)-bis-pyrazolate complex. According to the special geometry in the N,N',N''-tridentate ligand, containing two five-membered heterocycles, the complex deviates from an ideal square-planar coordination geometry; the N(pyrz)-Au-N(pyrz) angle is 160.8 (3)°, indicating a distortion of nearly 20°.
