AbstractHydrazine complexes of the compositions M(N/sub 2/H/sub 4/)/sub 2/ (Picrate)/sub 2/ H/sub 2/O (where M = Mn (II), Ni (II), Cu(II) or Zn(II), Co (N/sup 2/H/sup 4/) (Picrate)/sub 2/, Ni(N/sub 2/H/sub 4/)/sub 3/ (Picrate)/sub 2/, Zn(N/sub 2/H/sub 4/)/sub 4/ (Picrate)/sub 2/, and M/sup '/(N/sub 2/H/sub 4/)/sub 2/ (Picramate)/sub 2/ (where M/sup '/ = Mn(II), Fe(II), Co(II), Ni(II), Cu(II) or Zn(II) have been prepared and characterized by analysis, molar conductance, magnetic susceptibility, electronic and infrared spectral data. Molar conductance of the soluble complexes indicate that they are non-electrolytes in THF. Magnetic susceptibility and electronic spectral data suggest that all the complexes are spin-free octahedral except Co(N/sub 2/H/sub 4/) (Picrate)/sub 2/ which is tetrahedral. Infrared spectral studies show that hydrazine behaves as a monodentate ligand in its complexes with metal picramates and as a bidentate bridging ligand in all complexes with metal (II) picrates, except Zn(N/sub 2/H/sub 4)/sub 4/ (Picrate)/sub 2/ where it is monodentate.
