“…When the interaction potential is expressed as a multipole expansion and truncated at the dipolar term, the R"3 dependence of the solid-state transition discussed above is predicted. 23,21,22 As the distance between molecules increases, one would expect such a model, if anything, to improve, since long-range forces between molecules are associated with precisely the kind of interaction being considered here.…”

The polarized specular reflection spectra of a series of crystals containing columnar arrays of Pd(CN)42-ions have been determined. These crystals were selected so as to provide a variety of nearest-neighbor distances within the ionic columns. Absorption spectra derived via Kramers-Kronig analysis from the reflection spectra obtained when the electric vector of the incident radiation vibrates parallel to the stacking direction are reported. These spectra indicate the low-energy portion of the solution absorption region to be the origin of the strong solid-state absorption characteristic of these crystals. The implications of this finding with regard to models that have been proposed to describe the solid-state perturbations responsible for the spectral changes associated with the development of the characteristic crystal band in these and related d8 systems are discussed.The knowledge of the solution origin of the crystal regard to the evaluation of such models.

“…Especially, a one-dimensional superlattice consisting of linear metal chains, of which constituents are artificially arranged as designed, might be of particular interest not only for molecular engineering but for also coordination chemistry. Up to the present, there have been several reports for preparing a one-dimensional alloy using metal complexes. − However, many of these techniques are based on the crystal growth of the metal complex itself. Thus, it seems to be difficult to control the arrangement of constituent metals in a linear chain as designed.…”

Fabrication of a Superstructured One-Dimensional Alloy in a Thin Film Using Bis(dimethylglyoximato)metal(II)

We have investigated the fabrication of a superstructured one-dimensional alloy using bis(dimethylglyoximato)metal(II) (M(dmg)2, M = Pd, Pt) with a vacuum evaporation technique. It was found that coevaporation of these metal complexes gave a thin film of their mixed crystal. The films were quite transparent showing a strong d z 2 −p z transition band in the visible region, of which the peak wavelength subsequently varied in proportion to the mixing ratio. These results suggested that a linear alloy chain was formed in the film of the mixed crystal. A perpendicular orientation of the alloy chain axis could be obtained by depositing the mixed crystal on a KBr-cleaved surface. These findings make it possible to fabricate a one-dimensional superlattice in which several metal components are artificially arranged in a linear chain as designed. Pt(dmg)2 and Pd(dmg)2 were alternatively deposited on a KBr-cleaved surface. Peak shifts of the d z 2 −p z transition bands showed that a heterojunction between the platinum and palladium complexes could be formed in a linear alloy chain. It was revealed that the unit metal-chain length in a one-dimensional alloy could be tuned by the control of the deposited film thickness.
