Hydrothermal Syntheses and Crystal Structures of Two Complexes with 3,5- Dinitrosalicylate and 2,2′-Bipyridine Ligands

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 P1,a=5.581(4),b=12.071(8),c=12.88(1),α=92.10(3),β=96.73(3),γ =102.02(2)°,C17H10N4O7Cd,Mr=494.69,V=841(1)3,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 P21/c,a=8.604(3),b=23.88(1),c=8.894(3),β=102.45(1)°,C17H10N4O7Mn,Mr=437.23,V= 1785(1) 3,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 (Cd2O2) 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). The fluorescence properties and cyclic voltammetric behaviors of the complexes are also reported.
