  When trimethyl derivatives of aluminium, gallium and indium are reacted with dithiooxamides, , in a molar ratio, 2 moles of methane are set free, and monomeric bis(dimethylmetal)/dithiooxamides are formed. By 1H NMR, IR and Raman spectroscopy, two structural isomers have been established for these metalla complexes, both with a planar molecular backbone of two fused five-membered rings, but different

• Effects of Uniaxial Pressure and Shear on the Electrical Conductivity of Solid. II. Electrical Conductivity in Some Amorphous Coordination Polymers
  作者：Seiichi Kanda、Kuwako Ohkawa、Kenichi Yamashita、Nobuo Oda、Hideaki Chihara

  DOI：10.1246/bcsj.58.1619

  日期：1985.6

  Three amorphous coordination polymers, R2dtoaCu, where R=CH3, C6H5CH2, or cyclohexyl and dtoa=(N,N′-disubstituted dithiooxamidato), were prepared and the effect of uniaxial pressure on their electrical resistivities in the direction of the external pressure was measured. Application of the pressure up to 6×108 Pa caused an increase in the resistivity but, before reaching the equilibrium state, the resistivity exhibited a complicated time variation, which was not completely reversible upon pressure release as far as the measurement could trace. The results were explained on the basis of a model in which at least two competing processes occur. One of the processes is assumed to be reorientation of the two-dimensional network of molecules perpendicular to the applied pressure, which is a slow process and takes as long as hundreds of hours to reach the equilibrium. Activation energies of various processes were derived.
