The interaction of zinc(II) or cadmium(II) sulfate with 4,4'-bipyridine (bpy) or 4,4'-bipyridinethane (bpe) in the presence of 1,2-cyclohexanedionedioxime (NioxH(2)) resulted in four novel polymeric compounds with the compositions {[Zn(H2O)6](Zn(SO4)(2)(H2O)(2)(bpy)][Zn(SO4)(H2O)(3)(bpy)]}(infinity) (1), {[Zn(SO4)(NioxH(2))(bpy)]center dot 0.5H(2)O center dot DMF}(infinity) (DMF = N,N-dimethylfonnamide) (2), [Zn(SO4)(NioxH(2))(bpe)](infinity) (3), and [Cd(SO4)(NioxH(2))(bpe)](infinity) (4). Compounds were characterized by spectroscopic techniques and single crystal X-ray method. The chiral layer coordination polymer is the robust structural motif in 2-4. Although compounds 3 and 4 were isolated in the same crystallization conditions, the layers of opposite chirality constitute the achiral (3), and the layers of the same chirality result in chiral (4) architectures. All materials display blue luminescence upon excitation with ultraviolet light
