Abstract
A new complex [Cu(NCS)4 (N-Eim)4] [Cu(NCS)2 (N-Eim)2] (where N-Eim = N-ethylimidazole) has been synthesized and structurally characterized by single-crystal X-ray diffraction. The compound crystallizes in the Triclinic space group P−1 with the parameters: a = 8.7707(18) A, b = 10.712(2) A, c = 13.511(3) A, α = 104.73(3)°, β = 104.84(3)°, γ = 102.52(3)°, V = 1131.54(3) A3, with Z = 1 formula units. In the structure, the copper atoms all assume an elongated octahedral geometry with two distinct coordination environments; one is coordinated by four N-ethyl-imidazole ligands and two axial SCN groups, and another by two SCN groups and two N-ethyl-imidazole ligands. The two units form one infinite 1D zigzag chain along the [1 0 1] plane by two thiocyanate ligands from the [Cu(NCS)4 (N-Eim)4] units. The title compound, tetrakis(1-ethyl-1H-imidazole)diisothio cyanatocopper(II) bis(1-ethyl-1H-imidazole)diisothiocyanatocopper(II) has been synthesized and structurally characterized by single-crystal X-ray diffraction. In the structure, the copper atoms all assume an elongated octahedral geometry with two distinct coordination environments. The two units form one infinite 1D zigzag chain along the [1 0 1] plane by two thiocyanate ligands from the [Cu(NCS)4 (N-Eim) 4] units.
