The 1:1 mixture of Co(Brhfpip)₂ and D1py₂ gave isomeric diazocobalt complexes, 1 and 2, formulated by [Co(Brhfpip) ₂(D1py₂)]_n. Complexes 1 and 2 have zigzag and linear chain structures by the cis and trans coordination of pyridine units in D1py₂, respectively. After irradiation of microcrystalline samples, the generated carbene interacted with the cobalt ion to form ferromagnetic chains, 1c and 2c. Those isomeric chains exhibited slow magnetic relaxation with U_eff = 93 and 87 K and H_c = 20 and 13 kOe at 1.9 K for 1c and 2c, respectively.
