trans–[Ir₂(Cl)₂(CO)₂(μ₂-Dmpm)₂(MeO₂C)C≡C(CO₂Me)]

Formula Unicode styled: 
trans–[Ir₂(Cl)₂(CO)₂(μ₂-Dmpm)₂(MeO₂C)C≡C(CO₂Me)]
Compound name(s): 
(μ₂-dimethyl-acetylenedicarboxylate)-bis(bis(diphenylphosphino)-methane-P,P')-dicarbonyl-dichloro-di-iridium(Ir—Ir)
Central atom: 
Charge on formula unit (QN): 
0
Compound type: 
Notes: 

"The acetylene molecule is bound parallel to the metal-metal axis in a cis-dimetalated olefin geometry. Consistent with this, the geometries of the metalated carbons are reminiscent of sp² hybridization and the C-(5)-C(6) distance (1.344(8) Å) is close to that of a normal carbon-carbon double bond."
