catena-Poly[[bis(μ₄-hexafluoro­glutar­ato)­bis(tetrahydro­furan)tetrasilver(I)]-μ₂-4,4′-biphenyl­dicarbonitrile]

The title complex, [Ag₄(C₅F₆O₄)₂(C₁₄H₈N₂)(C₄H₈O)₂]_n, exhibits a one-dimensional chain structure propagated through inversion centres, with two crystallographically independent Ag^I atoms in the asymmetric unit. One of the Ag atoms has a distorted trigonal-pyramidal coordination, defined by two carboxyl O atoms from two hexafluoro­glutarate (HFG²⁻) anions, one N atom from 4,4′-biphenyl­dicarbonitrile and one apical O atom of tetrahydro­furan. The other Ag atom is coordinated by two O atoms from two HFG²⁻ anions.
