Abstract:
The two title complexes, [Cd{3,5-(NO2)(2)sal}2,2'-bipy)](n) 1 and [Mn{3,5(NO2)(2)sal}(2,2'-bipy)](n) 2 (3,5-(NO2)(2)sal = 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 P-(1) over bar, a = 5.581(4), b = 12.071(8), c = 12.88(1) angstrom, alpha = 92.10(3), beta = 96.73(3), gamma = 102.02(2)degrees, C17H10N4O7Cd, M-r = 494.69, V = 841(1) angstrom(3), Z = 2, D-c = 1.954 g/cm(3), F(000) = 488, mu = 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) angstrom, beta = 102.45(1)degrees, C17H10N4O7Mn, M-r = 437.23, V= 1785(1) angstrom(3), Z = 4, D-c = 1.627 g/cm(3), F(000) = 884, mu = 0.791 mm(-1), R = 0. 0471 and wR 0. 1250. Complex I possesses an infinite 1D polymeric chain structure consisting of the repeated basic four-membered ring units (Cd2O2) and eight-membered ring units (CdOCO)(2). Compound 2 displays a linear ID chain through Mn(II) atoms and bridging carboxylate groups of 3,5-dinitrosalicylic acid ligands with the Mn center dot center dot center dot Mn separation of 4.472(2) angstrom. The fluorescence properties and cyclic voltammetric behaviors of the complexes are also reported.
