A Three‐Component Modular Strategy to Extend and Link Coordination Complexes by Using Halogen Bonds to O, S and π Acceptors

Strategic extension! A modular strategy, involving the recognition and assembly of three molecular components, was used to decorate complexes of NiII and CoII with halogen bonds of I⋅⋅⋅S and I⋅⋅⋅O type. In addition to this rational implementation of halogen bonding to extend coordination structures, the resulting materials also demonstrate the self-assembly through I⋅⋅⋅π interactions as a means to form polymers based on coordination and halogen bonds (see graphic).
