Abstract:	The reaction (1 : 1) between A Me₂)Cl₂] and Hg(2-C₆H₄-N=NPh)₂] gives the complex (2-PhN=NC₆H₄)A MeC₂)Cl], which on treatment with AgClO₄ gives (2-Ph Me₂)]ClO₄. From this complex, the species (2-PhN=NC₆H₄)A Me₂)X] (X = CH₃COO, CN), or (2-PhN=NC₆H₄)A Me₂)L] (L = PPh₃, py) are obtained by reaction with the corresponding KX salts or neutral ligands. The crystal structure of (2-Ph Me₂)]AuCl₄] (obtained by metathesis between the corresponding perchlorate and tetramethylammonium salts) has been determined; the cation displays square-planar coordination with two cis-nitrogen (Au---N: 2.166(15), 2.140(14) Å) and two cis-carbon (Au---C: 2.021(16), 2.033(17) Å) atoms bonded to the gold atom.
