Five complexes [Co3(Hpmad)6]·(4‐sb)2·(CH3COO)2·(H2O)2 (1), [Co3(Hpmad)6]·(3‐sb)2·(CH3COO)2·(H2O)0.5 (2), [Co(Hpmad)2(4‐sb)]n (3), [Co(Hpmad)2(3‐sb)]n (4) and [Co(Hpmad)(SO4)(H2O)2]·H2O}n (5) [Hpmad is 2‐pyrimidineamidoxime, H2(4‐sb) is 4‐sulfobenzoic acid and H2(3‐sb) is 3‐sulfobenzoic acid], were prepared at room temperature. Complexes 1–5 were characterized by elemental analyses, single crystal
