内容記述(抄録等) | Acicular nickelous ethyl xanthate, Ni (EtX)_2, crystals often grow from the acetone solution with usual platy square crystals. The crystal structure of orthorhombic form corresponding to the platy square crystal has been determined by Franzini (1963). The acicular one found in the present work is determined to be triclinic by the x-ray method. The crystal structure has been solved by the Patterson method and refined using the 4-circle x-ray diffraction data. Space group: P1, a=8.835, b=10.299, c=8.143 A, α=91.81°, β=122.33°, γ=70.52°; Z=2. A residual factor is R=5.3% for observed 2048 structure factors. Four strong Ni-S bonds in the molecule and two weak bonds between neighbouring molecules make an octahedral coordination of NiS_6. These octahedra make chain structure sharing edges parallel to the c-axis, which is concordant with elongation habit of this acicular crystal. Crystallographically different two Ni (EtX)_2 molecules in the unit cell of the triclinic form and one kind of molecule in the orthorhombic form are very similar with each other. Hydrogen atom positions of ethyl group were determined on the map of difference Fourier synthesis.
