The reactions of TpylC(6)H(4)C CAuL (Tpyl = 2,2':6',2"-terpyridin-4'-yl; L = PPh3, CNXy; Xy = 2,6-dimethylphenyl) with MX2 center dot nH(2)O (M = Fe, X = ClO4; M = Co, X = BF4; M = Zn, X = TfO, ClO4) in a 2:1 molar ratio give complexes [M(TpylC(6)H(4)C CAuL)(2)]X-2. Similarly, the reactions of PPN[(TPYlC(6)H(4)C C)(2)Au] (PPN = (Ph3P)(2)N) with an equimolar amount of MX2 center dot nH(2)O give coordination oligomers [M-{TpylC6H4C C)(2)Au}]X-n (M = Fe, Zn, X = ClO4; M = Co, X = BF4). The complexes and oligomers have been isolated and characterized. The crystal structures of [Fe(TpylC(6)H(4)C CAuCNXy)(2)](ClO4)(2) and [Co (TpylC(6)H(4)C AuPPh3)(2)] (BF4)(2) have been determined by X-ray diffraction. The hydrodynamic sizes of complexes [M(TpylC(6)H(4)C CAuPPh3)(2)]X-2 and coordination oligomers [M{(TpylC(6)H(4)C C)(2)}Au}(n)X-n have been studied by NMR diffusion spectroscopy and dynamic light scattering measurements.
