Abstract
The synthesis of novel dinuclear nickel(II)–xanthate polyether macrocycles and dinuclear cobalt(III)–xanthate polyether cryptands is reported. The assemblies have been characterised by a range of spectroscopic techniques and in one case by X-ray crystal structure determination. Electrospray mass spectrometry provided evidence that the dinuclear nickel(II)–xanthate macrocycles form adducts with Group I metal cations and methyl viologen (MV 2+). The dinuclear cobalt(III)–xanthate cryptands also form adducts with Group I metal cations but did not interact with MV 2+.
