Modification of tetrathiafulvalene with an imidazolyl substituent as a hydrogen‐bond donor allows the generation of a hydrogen‐bonded 2:1 charge‐transfer complex with chloranil. This complex forms a three‐dimensional network with columnar stacking of each component and multiple S⋅⋅⋅S interactions (see picture). This strongly hydrogen‐bonded purely organic conducting material is the first to display metallic behavior.
