Abstract

The enantiomerisation pathway for {[Pt(thiourea)4]}F+ [a model for the C-4-symmetric [Pt(SU)(4)]SiF6 (SU = thiourea) complex] and derivatives is explored by density functional theory (B3LYP/LANL2DZp) and the activation barrier for the one-step process from C-4 to C-4' via a C-4 transition state is computed. The substitution of Pt2+ by Pd2+ and Ni2+ and the exchange of selenourea and tellurourea increase the barrier. (([[Pt(thiourea)(4)]}F+: 4.2 kcal/mol, {[Pd(thiourea)(4)f]}F+: 4.5 kcal/mol, {[Ni(thiourea)(4)]}F+: 7.6 kcal/mol, {[Pt(selenourea)(4)]F+: 5.3 kcal/mol, {[Pt(tellurourea)(4)]}F+: 8.8 kcal/mol).
