3d metal carbodiimides: nitrogen analogues of 3d oxides

600 °C: MnCl2(s) + ZnNCN(s) = ZnCl2(g) + MnNCN

While being thermodymatically unstable, transition metal carbodiimides can be kinetically stable and, thus, obtained under specific conditions. E.g. MnNCN is synthesized through a metathesis reaction that is driven by sublimation of ZnCl2.

Similar to oxides, 3d metal cabodiimides might provide new examples of solid-state chemistry/physics phenomena of the correlated 3d transition metals
