  Abstract: Under mild conditions CO2 reacts with   [Sr{N(PPh2)2}2](THF)3 to oxidatively cleave PPh2 groups,   resulting in the new ligand [N(CO2)3]3- in   [Sr6{O2CN(PPh2)2}6{N(CO2)3}2]. The Sr6 framework chem. fixates   twelve equiv. of CO2, half by the formation of two [N(CO2)3]3-   ligands and the other half by CO2 insertion to form the   unprecedented phosphanyl-substituted carbamate ligand   O2CN(PPh2)2.
