6 5 4. Theoretical Calculations DFT calculations on the model complex cation [Ag{(CpMo) 2 P 4 S} 2 ] + (I) were carried out using the Amsterdam Density Functional program (ADF) version [1] Scalar relativistic corrections were included via the Zero Order Regular Approximation (ZORA) method. [2] The generalized gradient approximation was employed, using the local density approximation of Vosko, Wilk, and Nusair [3] together with the nonlocal exchange correction by Becke [4] and nonlocal correlation corrections by Perdew. [5] The Slater-type orbital (STO) basis sets were of triple-ζ quality augmented with a single polarization function and two diffuse functions (ADF basis TZP++). The cores of the atoms were frozen up to 1s for C, 2p for P and S and 4p for Mo and Ag. Optimisations were performed without symmetry restraints with an integration grid of 4.0. Solvation effects were incorporated via the Conductor-like Screening Model (COSMO) [6] using acetonitrile as solvent. The relative energies of selected linkage isomers in the gas phase as well as in solution (acetonitrile as solvent) are given in Table 1. The gas phase optimised geometries of the cations Ia-m are depicted in Figure 3.
