Redetermination of [Cu₅Cl₁₀(n-C₃H₇OH)₂]

The structure of the title compound octa-μ-chloro-1:2κ⁴Cl, 2:3κ⁴Cl, 3:4κ⁴Cl, 4:5κ⁴Cl-dichloro-1κCl,5κCl- bis(propanol)-1κO, 5κO-pentacopper(II), consists of planar bibridged pentameric Cu₅Cl₁₀L₂ (L = n-propanol) units. Each Cu²⁺ ion assumes an approximate square-planar coordination geometry, with Cu—Cl distances ranging between 2.258 (2) and 2.297 (3) Å. The oligomers form stacks parallel to b through the formation of longer semicoordinate bonds which range in length from 2.687 (2) to 3.158 (3) Å. The stacking pattern leaves one semicoordinate site vacant on the Cu(3) atom. The stacks then aggregate into sheets lying parallel to the (01) planes through the formation of semicoordinate Cu(3)—Cl(5) bonds of 2.681 (2) Å. The n-propyl groups separate these sheets. Large atomic displacements of the C atoms [particularly for atoms C(2) and C(3)] indicate substantial disorder of the propyl group.
