Quantum chemical investigations Methods All molecular geometry optimizations for the decomposition of tris(amino)methanide [(H 2 N) 3 C - ] and tris(pyrazolyl)methanide [(Pz) 3 C - ] were performed with the Gaussian09 1 suite of programs at B3LYP 2 3 4 / aug-cc-pvtz or MP2 5 6 7 8 9 / aug-cc-pvtz level of theory. Vibrational analysis was performed at the same level of theory to confirm the nature of local structure minima. The decomposition of [{κ 1 C,κ 2 N-C(Pz Ph ) 3 } 2 Ca] was investigated with B3LYP/6-++31G** 10. Vibrational analysis was performed at the same level of theory as far as possible. The basis set superposition error were computed with the keyword counterpoise. Vibrational analysis was performed at the same level of theory to confirm the nature of the optimized stationary point. However, due to limited computational resources this was only possible for C1,C2, E1 and E2. 1 Gaussian 09, Revision A.02, M. J. Frisch, G. W. Trucks, H. B. Schlegel, G. E. Scuseria, M. A. Robb, J.
