Abstract: The crystal structure of the title compound has been determined from single-crystal X-ray diffractometer data. (C_5H_7S_2)_2[Cu_3I_5] crystallizes in space group I 2/a with α=1.8126(12), b=0.9302(2), c=1.4275(2)nm, β=101.51(1)°and z= 4. The full-matrix least-squares refinement gave R=0.043 for 1820 observed [I>3.0σ(I)] reflections. The crystal structure consists of (C_5H_7S_2) cations and [Cu_3I_5]_∞ anions of infinite I-bridged chains, the repeat unit of which contains one three-coordinated copper(I) atom, the ligand configuration being approximatively trigonal planar, and two four-coordinated copper(I) atoms, possessing the ligand configuration of tetrahedron. The Cu—Cu distances are 0.2528(2) and 0.2557(2) nm, respectively.
