catena-Poly[{di-μ-nitrato-1:2κ⁴O-bis[(triphenylphosphine-P)copper(I)]}-μ-4,4'-bipyridyl-N:N'] Tetrahydrofuran Solvate

A copper(I) complex with triphenyl­phosphine and 4,4′-bipyridine results in a one-dimensional polymer, {[Cu₂(NO₃)₂(C₁₈H₁₅P)₂(C₁₀H₈N₂)].2C₄H₈O}_n. The Cu centers are alternately bridged by nitrate counterions and bipyridine ligands. The four-membered Cu₂O₂ ring lies on an inversion center ( − x,  − y, −z) and the bipyridyl ligand lies on another inversion center ( − x,  − y, −z). The triphenyl­phosphine ligand coordinates to copper providing a distorted tetrahedral coordination environment, with bond lengths Cu1—P 2.168 (1), Cu—N 2.013 (3) and Cu—O 2.177 (2) and 2.147 (2) Å. The cavities between the chains contain tetrahydrofuran solvent molecules.
