Conclusions
-
1.
The reaction of platinum dicarbonyl with triarylphosphines has afforded the clusters Pt3(CO)3(PAr3)4 and Pt5(CO)6(PAr3)4.
-
2.
In aqueous-acetone solution, in the presence of ammonia, platinum dicarbonyl is present in the form [Pt3(CO)6]5 2−.
-
3.
In the first step of the reaction of triarylphosphites with [Pt3(CO)6]5 2− the clusters [Pt3(CO)6]3 2− and Pt3(CO)3(PAr3)4 are formed.
