The
reactions of TpylC<sub>6</sub>H<sub>4</sub>CCAuL
(Tpyl = 2,2′:6′,2″-terpyridin-4′-yl; L
= PPh<sub>3</sub>, CNXy; Xy = 2,6-dimethylphenyl) with MX<sub>2</sub>·<i>n</i>H<sub>2</sub>O (M = Fe, X = ClO<sub>4</sub>; M = Co, X = BF<sub>4</sub>; M = Zn, X = TfO, ClO<sub>4</sub>) in
a 2:1 molar ratio give complexes [M(TpylC<sub>6</sub>H<sub>4</sub>CCAuL)<sub>2</sub>]X<sub>2</sub>. Similarly,
the reactions of PPN[(TpylC<sub>6</sub>H<sub>4</sub>CC)<sub>2</sub>Au] (PPN = (Ph<sub>3</sub>P)<sub>2</sub>N) with an equimolar
amount of MX<sub>2</sub>·<i>n</i>H<sub>2</sub>O give
coordination oligomers [M{(TpylC<sub>6</sub>H<sub>4</sub>CC)<sub>2</sub>Au}]<sub><i>n</i></sub>X<sub><i>n</i></sub> (M = Fe, Zn, X = ClO<sub>4</sub>; M = Co, X = BF<sub>4</sub>). The complexes and oligomers have been isolated and characterized.
The crystal structures of [Fe(TpylC<sub>6</sub>H<sub>4</sub>CCAuCNXy)<sub>2</sub>](ClO<sub>4</sub>)<sub>2</sub> and [Co(TpylC<sub>6</sub>H<sub>4</sub>CCAuPPh<sub>3</sub>)<sub>2</sub>](BF<sub>4</sub>)<sub>2</sub> have been
determined by X-ray diffraction. The hydrodynamic sizes of complexes
[M(TpylC<sub>6</sub>H<sub>4</sub>CCAuPPh<sub>3</sub>)<sub>2</sub>]X<sub>2</sub> and coordination oligomers
[M{(TpylC<sub>6</sub>H<sub>4</sub>CC)<sub>2</sub>Au}]<sub><i>n</i></sub>X<sub><i>n</i></sub> have been studied by NMR diffusion spectroscopy and dynamic light
scattering measurements.
