A novel one-dimensional polymeric complex of a tetraaza-macrocycle–copper(II) unit with a [Cu(C2O4)2(CH3CN)]2–bridging anion

Abstract

In the title compound, catena-poly­[(5,12-di­methyl-7,14-di­phenyl-1,4,8,11-tetra­cyclo­tetra­decane)copper(II) bis­[[(5,12-di­methyl-7,14-di­phenyl-1,4,8,11-tetra­cyclo­tetra­decane)copper(II)]-μ-oxalato-[(aceto­nitrile)copper(II)]-μ-oxalato] diperchlorate], [Cu(C24N4H36)][Cu4(C2O4)4(C24N4H36)2(CH3CN)2](ClO4)2, the {(CuC24N4H36)-μ-[Cu(C2O4)2(CH3CN)]}2n component is a one-dimensional chain polymeric complex of copper(II) bridged by [Cu(C2O4)2(CH3CN)]2−. In the structure, there are three types of copper(II) coordination environment. The coordination environment around the CuII atom in (CuL)2+ of the polymer (L is 5,12-di­methyl-7,14-di­phenyl-1,4,8,11-tetra­cyclo­tetra­decane) is an elongated octahedron, the CuII atom in [Cu(C2O4)2(CH3CN)]2− exhibits a square-based pyramidal geometry, while the CuII atom in the (CuL)2+ counter-cation exhibits a square-planar geometry. The Cu atoms coordinated by L lie on inversion centers. The Cu⋯Cu distances are 6.092 (4) and 5.551 (4) Å.
