NMe 2 )]Cl have been synthesised and characterised. The phosphine, 2-(diphenylphosphino)benzoic acid, has been employed for the first time in gold chemistry. This ligand is potentially bidentate through bonding of the phosphine and carboxylate groups. The X-ray structure of the complex chloro[2-(diphenylphosphino) benzoic acid]gold(I) has been elucidated and the bond lengths encountered show great similarity to those of chloro(triphenylphosphine)gold(I).

Biological tests for anti-fungal and anti-bacterial activity demostrate that [2-(PPh 2 )C 6 H 4 CO 2 H]AuCl exhibits broad spectrum activity against a range of organisms.
