Abstract

The first application of nonempirical molecular electronic structure theory to a realistic transition-metal carbene complex is reported. The system chosen was (CO)3NiCH2, methylene(tricarbonyl)nickel(0). All studies were carried out at the self-consistent-field (SCF) level. A large and flexibly contracted basis set was chosen, labeled Ni(15s 11p 6d/11s 8p 3d), C,O(9s 5p/4s 2p), H(5s/3s). The critical predicted equilibrium geometrical parameters were R[Ni-C(methylene)] = 1.83 Å, θ(HCH) = 108°. The sixfold barrier to rotation about the Ni-C(methylene) axis is small, ∼0.2 kcal. The electronic structure of (CO)3NiCH2 is discussed and compared with those of the "naked" complex NiCH2 and the stable Ni(CO)4 molecule.
