Tetrahydrofuran (THF), methanol, ethanol, n-hexane, 1,4-dibromobutane, 2,2'-bipyridine (bpy), N,N-tetraethylthiuram disulfide (TD; Tokyo Kasei Organic Chemicals, Tokyo, Japan), silver nitrate (AgN[O.sub.3]), potassium thiocyanate (KCNS), hydrochloric acid (HCl) and copper(I) bromide (CuBr; Kanto Chemicals, Tokyo, Japan) were used as received.
For example, [bis(1,10-phenanthroline) L2copper(II)] (L = cis-5-norbornene-endo-2, 3-dicarboxylic acid; 2,2'-bipyridine; dicyanamide, adenine, and thymine) is well known for its numerous biological activities such as anti-Candida [21], antimycobacterial, and antimicrobial [23] activity.

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).sub.3]].sup.2+] in the [Ag.sup.+] catalysed oxidation by peroxodisulphate ([S.sub.2][O.sup.2-.sub.8]).
The addition complexes also exhibited additional peaks for the aromatic protons of the donorligands in the regions 7.24-7.64 (triphenylphosphine), 7.25-8.99 (1,10-phenanthroline), 7.29- 8.51 (pyridine), and 7.09-8.59 (2,2'-bipyridine).
