Hexarhodiumhexadecacarbonyl can be obtained by reaction of Dirhodiumtetraacetat with carbon monoxide and water

Are obtained, or by Druckcarbonylierung of rhodium (III ) chloride trihydrate with carbon monoxide.

Properties

Hexarhodiumhexadecacarbonyl is a violet brown (larger crystals appear black), air-stable crystalline solid with a surface gloss. It is insoluble in aliphatic solvents, slightly soluble in all other common solvents. To dilute acids and alkalis it is resistant. When heated above 200 ° C it begins to decompose. Of air forms above 220 ​​° C a glossy film on the metal surface.
