The reaction of M(S₂O₆) (M = Cu^II, Ni^II, and Co^II) with 4,4'-bipyridine-N,N'-dioxide (bpdo) results in the formationof novel 3D, 2D, and mononuclear complexes. Complex 1, {[Cu(H₂O)(bpdo)₂](S₂O₆)(H₂O)}_n, is a 2-D wavelikepolymer with the Cu^II ion located on a 2-fold axis and having a distorted square-pyramidal coordination sphere.With Co^II and Ni^II, 3-D complexes, {[M(bpdo)₃](S₂O₆)(C₂H₅OH)₇}_n [M = Co^II (2), Ni^II (3)], were obtained. The metalatoms are situated on centers of symmetry and have octahedral environments coordinated to six bpdo molecules.The same reaction in aqueous solution with a metal/ligand ratio of 1:1 results in the formation of mononuclearcomplexes, {[M(bpdo)(H₂O)₅](SO₄)(H₂O)₂} [M = Co^II (4), Ni^II (5)], accompanied by the decomposition of the dithionateanions S₂O₆^2- to sulfate anions SO₄^2-.
