An infrared spectroscopic study on the Hofmann-diam-type 1,9-diaminononanemetal(II) tetracyanonickelate(II)-aromatic guest clathrates: M(H2N(CH2)(9)NH2)Ni(CN)(4)center dot G (M = Cd or Ni; G = benzene, naphthalene, anthracene or phenanthrene

Abstract

IR spectra of M(1,9-Diaminononane)Ni(CN)(4).G (M = Cd or Ni; G = benzene, naphthalene, anthracene or phenanthrene) are reported. The spectral data suggest that the host structures in these clathrates are similar to those of Hofmann-alpha, omega -diaminoalkane type clathrates.
