The importance of the thiadiazole ring : While electrostatic interactions between the thiadiazole rings is responsible for the 2D close packing in the solid‐state structure of tetrakis(thiadiazole)porphyrazine (TTDPzH 2 , see X‐ray crystal structure), the formation of a coordination bond between the ring and the cobalt ion results in the cobalt derivative TTDPzCo having a chain structure.
