Bis(bromogold(I)) bis(diphenylphosphino)methane
Bis(bromogold(I)) bis(diphenylphosphino)methane (CAS 72476-68-7; formula C25H22Au2Br2P2; molar mass 938.13 g/mol), commonly abbreviated dppm(AuBr)2, is a dinuclear gold(I) complex in which a bis(diphenylphosphino)methane ligand bridges two linear bromogold(I) centres. Supplied as a research-grade crystalline solid (m.p. 275-278 °C), it serves chiefly as a precursor and building block in organometallic and coordination chemistry, where its labile bromide ligands allow access to a wide range of dinuclear gold(I) compounds.

Precursor for dinuclear gold(I) complexes
The bridging dppm ligand holds two gold(I) centres in close proximity, making this complex a convenient starting material for assembling binuclear gold structures. Its bromide ligands are readily exchanged, providing entry to numerous derivatives.
Organometallic and coordination chemistry research
It is used as a defined gold(I) phosphine reagent in academic and industrial laboratories. Researchers value the predictable geometry imparted by the methylene-bridged bisphosphine framework.
Studies of aurophilic Au···Au interactions
The proximity of the two gold centres enforced by the dppm bridge makes derivatives of this complex useful for investigating gold-gold (aurophilic) interactions and related structural chemistry.
Photoluminescent gold(I) compounds
Dinuclear gold(I) phosphine complexes of this type are of interest for their photophysical behaviour, and the reagent is employed in preparing luminescent gold(I) species for study.
Homogeneous gold catalysis research
As a member of the gold(I) phosphine family, it is explored within homogeneous catalysis and ligand-design programmes. Specific catalytic performance depends on the system under investigation.
