The electronic spectra of 1 and 2 in DMF solutions showed that the two complexes have broad absorption charge transfer bands [LMCT i.e. charge transfer from dithiolate to Ru? or LL′CT, that is, charge transfer from dithiolate to 2,2′ bipyridine] in the visible region. Compared with 1, the LMCT or LL′CT band for 2 shifts to low frequency. The results of electrochemistry of the two complexes in DMF are consistent with that of the electronic spectra.展开更多

It crystallizes in triclinic with space group P1. The crystallographic data of the compound are: a=0.777 1(2) nm, b=1.043 4(3) nm, c=1.082 7(3) nm, α=71.403(4)°, β=80.946(5)°, γ=88.794(4)°. The 1D chainlike structure was connected by π-π interaction between phenyl rings, leading to a 2D layered network. The lattice water and the NO3- anions were involved between the layers, therefore the 2D layered structure further extended to an intricate 3D framework. CCDC: 257100.展开更多
