Abstract

A CaI synthon with superbulky β-diketiminate ligands (BDI*) and a N22− dianion, [(BDI*)Ca]2(N2), is key to the synthesis of binuclear (BDI*)Ca(μ2-O2)Ca(BDI*) and (BDI*)Ca(μ2-O)Ca(BDI*) complexes. The Ca oxide complex is particularly unstable in solution and was only accessible by a solvent-free reaction between solid [(BDI*)Ca]2(N2) and N2O gas.
