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=Ni^Ⅱ, Co^Ⅱ, Mn^Ⅱ）, 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.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.
