Abstract
[RhPy4Cl2]4[Re6S8(CN)6]⋅1.5H2O (Py is pyridine) was investigated by X-ray analysis. In the cluster anion, the Re-Re distances vary from 2.6063(2) Å to 2.6125(2) Å. For two crystallographically independent complex cations, the distances are 〈Rh-N〉 2.060 Å and 〈Rh-Cl〉 2.336 Å. The motif of the three-layered close packing was found; the [Re6S8(CN)6]4- anions follow the vertices of a rhombohedron with the parameters ac ≈ 15.5 Å and αc ≈ 61°.
