Here we describe the formation of a trigonal prismatic cage, utilizing 2‐formyl‐1,8‐naphthyridine subcom‐ ponents to bind pairs of silver(I) ions in close proximity. This cage is the first example of a new class of subcomponent self‐ assembled polyhedral structures having bimetallic vertices, as opposed to the single metal centers that typically serve as structural elements within such cages. Our new cage self‐as‐ sembles around a pair of anionic templates, which are shown by crystallographic and solution‐phase data to bind within the central cavity of the structure. Many different anions serve as competent templates and guests. Elongated dianions, such as the strong oxidizing agent peroxysulfate, also serve to tem‐ plate and bind within the cavity of the prism. The principle of using subcomponents that have more than one spatially close, but non‐chelating, binding site may thus allow access to other higher‐order structures with multi‐metallic vertices.
