The trans effect 反位效应

WebThe trans effect is explained in terms of σ-donation and π-back-donation whose relative strengths are quantified by the changes of electron occupations of 5d platinum atomic orbitals. The σ-donation strength is linearly correlated with the Pt H 2 O (leaving ligand) bond length (trans influence).
