Gold(III) complexes with 2-(N,N-dimethylaminomethyl)phenyl (damp(-)). Syntheses and structures of [Au(damp-C,N)Cl-2], [Au(damp-C,N)(OOCCH3)(2)] and [Au(damp-C,N)(mnt)] (mnt(2-) equals 1,2-dicyanoethene-1.2-dithiolate)

Dichloro-2-(N,N-dimethylaminomethyl)phenylgold(III), [Au(damp-C,N)Cl-2], was prepared by the reaction of [Hg(damp)Cl] with Na[AuCl4] and crystallizes monoclinic, space group P2(1)/c a = 7.896(3), b = 9.487(2), c = 15.107(6) Angstrom, beta = 100.22(3)degrees, Z = 4. The crystal structure consists of monomeric [Au(damp-C,N)Cl-2] units with square-planar coordinated gold atoms. The shortest Au-Au distances are 4.977 Angstrom. [Au(damp-C,N)(OOCCH3)(2)] can be synthesized by the reaction of [Au(damp-C,N)Cl-2] and AgOOCCH3 in CH2Cl2. Single crystals of the composition [Au(damp-C,N) (OOCCH3)(2)] 0.5 H2O were obtained from moist CH2Cl2: monoclinic, space group C2/c, a=16.626(8), b=10.640(1), c=16.271(7) Angstrom, beta = 91.90(2)degrees, Z = 8. The gold atom is square-planar coordinated. The acetato ligands are bound monodentately. The solvent water forms strong hydrogen bridges to the complex molecules in the solid state structure. The chloro ligands in [Au(damp-C,N)Cl-2] can easily be replaced by dianionic chelate ligands. The reaction with Na(2)mnt (mnt(2-) = 1.2-dicyanoethene-1.2-dithiolate) gives in almost quantitative yield the neutral complex [Au(damp-C,N)(mnt)], which crystallizes orthorhombic, space group Pna2(1) with a = 7.651(1), b = 14.476(1), c = 13.353(1) Angstrom, Z = 4.
