Orbitals were visualized using Multiwfn 3. The coordination geometry as determined using SHAPE2.1. Charge decomposition analysis (CDA) is one of the methods to analyze donor-acceptor interactions of each fragment of complexes. Here, We took complex 2 to three parts: Gd ion, Pt ions, and PhSAc ligands. CDA was performed on Multiwfn 3.7. 31a
