catena-Poly[[copper(I)-di-μ-trans-1-(2-pyrid­yl)-2-(4-pyrid­yl)ethyl­ene-κ²N²:N⁴;κ²N⁴:N²] tetra­fluoro­borate]

In the title complex, {[Cu(C₁₂H₁₀N₂)₂]BF₄}_n, each copper(I) centre is tetra­hedrally coordinated by N atoms from four bridging trans-1-(2-pyrid­yl)-2-(4-pyrid­yl)ethyl­ene (TPPE) ligands. The ligands bridge adjacent copper(I) centres to form one-dimensional folded chains. Adjacent uniform chains are further inter­linked into a three-dimensional framework through weak C—H...F inter­actions.
