  "abstract": "Incorporation of secondary, effectively Lewis acidic metal cations into heterometallic complexes is a useful strategy for tuning chemical properties and reactivity, but addressing the origins of metal-driven tunability and quantitative correlation of metal-focused data with computational modeling have not received the attention they deserve. Here, the synthesis and characterization of a series of diamagnetic complexes containing platinum(ii) and secondary cations (K+, Sr2+, and Lu3+) are reported, along with nuclear magnetic resonance (NMR) measurements of 195Pt chemical shifts (δ195Pt). Similar to related species, the spectroscopic and electrochemical properties of the complexes depend on the Lewis acidity, or charge density, of the secondary cations; the change in δ195Pt was found to be particularly well correlated with Lewis acidity and was therefore studied in detail. Computational investigations of the 195Pt NMR data reveal that the secondary cations induce changes in electron donation to platinum from bridging phenoxide moieties that lead to the experimental chemical shifts. In sum, the results both (i) establish a quantitative model for understanding cation-driven tuning in complexes of this type as well as (ii) demonstrate the usefulness of 195Pt NMR as tool for studying Pt-heterometallic compounds.",
