Ribbon‐type columns linked to form a network are found in the crystal structure of 1 , R = Br. This compound differs significantly from the Kekulé‐type analogue 2 in terms of its electron affinity and the position of its UV/VIS absorption maximum. The monoselenium analogues of 1 were also synthesized and characterized.
