Redetermination of [Cu5Cl10(n-C3H7OH)(2)]

The structure of the title compound, octa-mu-chloro-1:2 kappa(4)Cl, 2:3 kappa(4)Cl, 3 kappa(4)Cl, 4:5 kappa(4)Cl-dichloro-1 kappa Cl, 5 kappa Cl-bis(propanol)-1 kappa 0, 5 kappa O-pentacopper(II), consists of planar bibridged pentameric Cu(5)Cl(10)L(2) (L = n-propanol) units. Each Cu2+ ion assumes approximate square-planar coordination geometry, with Cu-Cl distances ranging between 2.258(2) and 2.297(3) Angstrom. 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) Angstrom. The stacking pattern leaves one semicoordinate site vacant on the Cu(3) atom. The stacks then aggregate into sheets lying parallel to the ((1) over bar 01) planes through the formation of semicoordinate Cu(3)-Cl(5) bonds of 2.681 (2) Angstrom. 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 groups.
