摘要

Three novel compounds [Ni(en)3](ndt)·H2O (1), [Co(en)3](ndt)·H2O (2) and [Mn(en)3](ndt)·H2O (3) (en=ethylenediamine, ndt= 1,5-naphthalenedithiolate)have been synthesized under hydrothermal conditions. The structures were characterized by single crystal X-ray diffraction and all belong to monoclinic space group Cc. The [M(en)3]2+ cations (M=Niu, CoⅡ, MnⅡ), ndt anions and crystallized water molecules assemble an iso-structural three-dimensional network through H-bonding interactions. Optical absorption properties and band gaps of such three compouds were determined with UV/Vis/NIR diffuse reflectance spectra.
