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)]--oxalato-[(acetonitrile)copper(II)]--oxalato] diperchlorate], [Cu(C₂₄N₄H₃₆)][Cu₄(C₂O₄)₄(C₂₄N₄H₃₆)₂(CH₃CN)₂](ClO₄)₂, the {(CuC₂₄N₄H₃₆)--[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 Cu^II 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 Cu^II atom in [Cu(C₂O₄)₂(CH₃CN)]^2- exhibits a square-based pyramidal geometry, while the Cu^II atom in the (CuL)²⁺ counter-cation exhibits a square-planar geometry. The Cu atoms coordinated by L lie on inversion centers. The CuCu distances are 6.092  (4) and 5.551  (4)  Å.
