Abstract
The crystal and molecular structure of the title compound, C20H8N4S12Ni, is reported. Crystals are triclinic, space groupP¯1 (No. 2) withz=1 in a cell of dimensionsa=8;482(2),b=7.950(2),c=9.976(2) Å,α=95.64(2),β=98.60(2), and γ=87.65(2)°. The structure was solved by Fourier methods and refined by the method of least squares toR=0.033 for 2027 unique reflections. The Ni atom has an approximate square-planar configuration with Ni-S(1)=2.179(1), Ni-S(2)=2.175(1) Å, and the S(1)-Ni-S(2) bite angle of 91.89(4)°. The anions and the cations form a mixed stack (DAD-DAD-⋯) along the diagonal of theab plane, showing the possibility of unusual electrical behavior.
