Four new Hofmann-type clathrates of the form M(bpa)(2)Ni(CN)(4). 2m-xylene (M = Mn , Fe , Co and Ni; bpa = 1,2-bis(4-pyridyl)ethane) have been synthesized and characterized by vibrational spectroscopy. The M(bpa)(2)Ni(CN)(4) (M = Fe and Co) host structure is similar to the classical Hofmann-type host framework composed of layers of a two dimensional catena-metal tetra-mu -cyanonickelate(II) network, but in M(bpa)(2)Ni(CN)(4) (M = Mn and Ni), the Ni(CN)(4) moiety behaves as a bidentate -[NC-Ni(CN)(2)-CN-]- unit in the host framework.
