Abstract

Calculations of charge density and the electric field gradient tensor at the iron nucleus by means of ab initio LCAO SCF, MS-X_α, SCC-X_α and IEHT methods for iron carbonyls Fe(CO)n, n=1-5, are presented. The calculated EFG values for the closed-shell molecule Fe(CO)5 show reasonable agreement with experiment while the values obtained for the open-shell molecules Fe(CO)n, n=1-4, significantly depend on the calculational method. Ab initio results, though using a minimal basis set, are closer to experimental data than X_α and IEHT results.
