Abstract

Here we report that attempted preparation of low-valent Ca^I complexes in the form of LCa-CaL (where L is a bulky b-diketiminate ligand) under dinitrogen (N2) atmosphere led to isolation of LCa(N2)CaL, which was characterized crystallographically. The N2²- anion in this complex reacted in most cases as a very potent two-electron donor. Therefore, LCa(N2)CaL acts as a synthon for the low-valent Ca^I complex LCa-CaL, which was the target of our studies. The N2²- anion could also be protonated to diazene (N2H2) that disproportionated to hydrazine and N2. The role of Ca d orbitals for N2 activation is discussed.
