Abstract: 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 (HFG^2-) 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 HFG^2- anions.
