Abstract

Mixed crystals of the one-dimensional metal complexes, bis(dimethylglyoximato)platinum(II) and bis(diethylglyoximato)platinum(II), were synthesized by a coevaporation technique. The continuous energy shift of the d-p transition was observed in the UV-vis absorption spectra of the coevaporated films. This energy shift shows that despite the difference in the crystal lattices between the two precursor complexes, both the metal complexes had mixed into the same column forming one-dimensional superstructures. Conventional X-ray diffraction and total reflection X-ray diffraction measurements showed that the anisotropic variation of the lattice constants depends on the mixing ratio. While the lattice constant parallel to the columns was approximately proportional to the mixing ratio, the variation of the constants perpendicular to the columns deviated substantially from a linear relation. This indicates that the one-dimensional framework of the mixed columns was maintained even though there is significant lattice mismatch between the precursor metal complexes.
