The structure of [Ni(i-PrXa)2] (i-Pr = i-C3H7, Xa = S2CO-) was solved by the heavy-atom method and refined anisotropically to R = 0.044 for 985 unique observed reflections. The compound crystallizes in the P21/c space group with a = 8.879(2), b = 6.086(1), c = 13.203(3) Å, β = 94.74(3)°, V = 711.0(3) Å3, T = 296 K, Z = 2. The molecule contains the NiS4 chromophore with an approximately planar configuration of the four sulfur atoms around the Ni(II). The Ni atom is located in the centre of symmetry.
