Abstract Chiral and non‐chiral ferrocenyldithiophosphonates [ t BuNH 3 ][Fe(η 5 ‐C 5 H 5 ){η 5 ‐C 5 H 4 P(O R )S 2 }] were prepared from [Fe(η 5 ‐C 5 H 5 ){η 5 ‐C 5 H 4 PS(μ‐S)}] 2 and the respective alcohol R OH [ R = bornyl ( 1 ), myrtenyl ( 2 ), adamantyl ( 3 )] and t BuNH 2 as base. The reaction with [AuCl(tht)] (tht = tetrahydrothiophene) gave the corresponding chiral ( 1a , 2a ) and non‐chiral ( 3a ) heterobimetallic dimeric gold(I) ferrocenyldithiophosphonato complexes [Au{Fe(η 5 ‐C 5 H 5 )(η 5 ‐C 5 H 4 P(O R )(μ‐S) 2 )}] 2 [ R = bornyl ( 1a ), myrtenyl ( 2a ), adamantyl ( 3a )]. Compounds 1 – 3 and 1a – 3a were characterised spectroscopically (IR, 1 H, 13 C, 31 P NMR) and by mass spectrometry, and the chiral heterobimetallic dimeric gold(I) ferrocenyldithiophosphonato complex 1a was also structurally characterised by X‐ray crystallography.
