An infrared spectroscopic study on the Hofmann-diam-type 1,12-diaminododecanemetal(II) tetracyanonickelate(II)-aromatic guest clathrates: M(H2N(CH2)(12)NH2)Ni(CN)(4)center dot G(M=Co, Ni or Cd; G = benzene, naphthalene, anthracene, phenanthrene or biphenyl)

Abstract

Three Hofmann-diaminododecane-type clathrates of the form M(1,12-diaminododecane) Ni(CN)(4).G (M = Co, Ni or Cd; G = benzene, naphthalene, anthracene, phenanthrene or biphenyl) have been prepared in powder form. The 1,12-diaminododecane molecules in the host lattice permit the inclusion of bulky guest molecules. The spectral features suggest that these compounds are similar in structure to the other Hofmann-diam-type clathrates.
