Complementary electronic properties of inorganic and organic halogen species are exploited in the design of molecular networks that employ MX⋅⋅⋅X′C halogen bonds. The dominance of electrostatic effects in this type of interaction over other energy terms, such as charge transfer, is demonstrated by the study of a series of eight isostructural compounds (4‐X′pyH) 2 [CoX 4 ] (see picture; X=Cl, Cl/Br, Br, I; X′=Cl, Br).
