Abstract
The phosphido-amido complex (I) and excess CO2 (II) react to give the mixed-ligand complex (III) with a Mo-Mo triply bond.
ChemInform Abstract
The phosphido-amido complex (I) and excess CO2 (II) react to give the mixed-ligand complex (III) with a Mo-Mo triply bond. The phosphinecarboxylate and the carbamate ligands are bound in an η2 fashion. (III) unexpectedly decomposes to yield the title complex (IV), which crystallizes as its benzene disolvate in the space group P21/n with Z=2.
