The reaction of (diphoe)Pt(CH2CN)(OH) and trans-(PBz3)2Pt(Ph)(OH) with CO2 is reported as producing dimeric, bridged carbonato complexes of the type: P4Pt2(R)2(CO3). The crystal and molecular structure of (PBz3)4Pt2(Ph)2(μ-CO3)·(toluene) is also reported, showing η1, η1 bonding. The reaction is recognized to proceed in a stepwise fashion through bicarbonato intermediates.

Abstract
The reaction of (diphoe)Pt(CH2CN)(OH) and trans-(PBz3)2Pt(Ph)(OH) with CO2 is reported as producing dimeric, bridged carbonato complexes of the type: P4Pt2(R)2(CO3). The crystal and molecular structure of (PBz3)4Pt2(Ph)2(μ-CO3)·(toluene) is also reported, showing η1, η1 bonding. The reaction is recognized to proceed in a stepwise fashion through bicarbonato intermediates.
