The HSAB theory represents a textbook knowledge of BSc-grad students, which has a great contribution to the methodological pedagogy of the Chemistry, rather than to understand comprehensively the electronic effects and coordination capability of silver ion(s).
Thus, an adequate and reliable knowledge of this issue as well as answer to your question can be provided when there is carried out a complementary high singly crystallographic XRD and quantum chemical, both theoretical and experimental analyses.
Thus, there is needed design and synthesis of inorganic crystals of salts of AgI-ion with the shown in your posting counterions, and their analyses by the aforementioned methods as it has been shown, for instance, in refs. [1,2].
