抄録

Single crystals of complex of Ni(II), bis(O-propyldithiocarbonato-κ²S,S′)(3,5-lutidine-κN)nickel(II) [Ni(S₂COCH₂CH₂CH₃)_2-(C₇H₉N)₂] have been synthesized by the reaction of bis(O-propyldithiocarbonato)nickel(II) with 3,5-lutidine in acetone, and its structure elucidated by the single-crystal X-ray diffraction method. The complex crystallizes in the triclinic space group P1 with unit-cell parameters: a = 7.008(5), b = 9.546(5), c = 10.621(5)Å, α = 87.484(5)°, β = 72.927(5)° and γ = 75.686(5)°. The crystal structure was solved by direct methods and refined by full-matrix least-squares procedures to a final R-value of 0.0371 for 2074 observed reflections. The two pyridine rings are coplanar, and are held almost perpendicular to the dithiocarbonato groups. The compound has a trans octahedral geometry.
