This work details the synthesis of a series of isostructural lanthanide dicyanoaurates complexes containing the ancillary ligand 2,2'-bipyridine
. Syntheses were carried out by reaction of Ln3+ triflate salts and potassium dicyanoaurate with 2,2'-bipyridine
(bpy) resulting in the compound, [Ln(C10H8N2)(H2O)4(Au(CN)2)], (Ln=Tb and Gd).
In this study, the following complexes were used: sodium (2,2'-bipyridine
)oxidobisperoxidovanadate(V) octahydrate, Na[VO[([O.sub.2]).sub.2](2,2'-bpy)] x 8[H.sub.2]O, marked as V (453.9 g/mol); bis(2,2'-bipyridine
)oxidovanadium(IV) sulfate dihydrate, [VO(S[O.sub.4])(2,2'-bpy)] x 2[H.sub.2]O, marked as B (511.21 g/mol); and bis(4,4'-dimethyl-2,2'-bipyridine)oxidovanadium(IV) sulfate dihydrate, [VO[(4,4'-Me-2,2'-bpy).sub.2]]S[O.sub.4] x 2[H.sub.2]O marked as Bm (567.21 g/mol).
The present investigation has been undertaken to fix the role of substrate [[Fe[(2,2'-bipyridine
