Abstract:
The two title complexes, [Cd{3,5-(NO2)2sal}(2, 2′-bipy)]n 1 and [Mn{3,5-(NO2)2sal}(2, 2′-bipy)]n 2 (3,5-(NO2)2sal = 3,5-dinitrosalicylate, 2,2′-bipy = 2,2′-bipyridine), were synthesized by the hydrothermal reaction and structurally characterized. Complex 1 crystallizes in triclinic, space group P1̄, a = 5.581(4), b = 12.071(8), c = 12.88(1) Å, α = 92.10(3), β = 96.73(3), γ = 102.02(2)°, C17H10N4O7Cd, M r = 494.69, V = 841(1) Å3, Z = 2, Dc= 1.954 g/cm3, F(000) = 488, μ = 1.353 mm-1 R = 0.0248 and wR = 0.0761. Complex 2 crystallizes in monoclinic with space group P2 1/c, a = 8.604(3), b = 23.88(1), c = 8.894(3) Å, β= 102.45(1)°, C17H10N4O7Mn, M r = 437.23, V = 1785(1) Å3, Z = 4, Dc = 1.627 g/cm3, F(000) = 884, μ = 0.791 mm-1, R = 0.0471 and wR = 0.1250. Complex 1 possesses an infinite 1D polymeric chain structure consisting of the repeated basic four-membered ring units (Cd2O 2) and eight-membered ring units (CdOCO)2. Compound 2 displays a linear 1D chain through Mn(II) atoms and bridging carboxylate groups of 3,5-dinitrosalicylic acid ligands with the Mn⋯Mn separation of 4.472(2) Å. The fluorescence properties and cyclic voltammetric behaviors of the complexes are also reported.
