Unexpected salt‐carrier properties are displayed by the calcium porphyrin presented here. The treatment of the free porphyrin with activated calcium metal gives a 1:1 complex in which the calcium ion is coordinatively unsaturated. Addition of [CaI 2 (thf)] then results in the formation of a double‐decker structure (see picture, Ar= tert ‐butylphenyl), which has been characterized by X‐ray crystallographic analysis.
