of these complexes with CO and CO2 is reported, including the squarate complex [U(COTTIPS2)(IndMe6)]2(μ-C4O4), IR data on the long-lived carbonyl complex [U(COTTIPS2)(IndMe7)(CO)] and the carbonate complex [U(COTTIPS2)(CptBu)]2(μ-η1:η2-CO3). The Solid-G algorithm has been to assess the steric properties of these and previously reported mixed-sandwich complexes in the solid state and correlate these properties
