title: catena-Poly[[di-mu-benzoato-kappa4O:O'-disilver(I)]-mu-N,N'-bis(2-fluorobenzylidene)butane-1,4-diamine-kappa2N:N'].
abstract: The title complex, [Ag(2)(C(7)H(5)O(2))(2)(C(18)H(18)F(2)N(2))](n), is a dinuclear silver(I) compound with one inversion centre between pairs of Ag atoms and another at the mid-point of the central C-C bond in the butane-1,4-diamine moiety. Each of the smallest repeat units consists of two silver(I) cations, two benzoate anions and one N,N'-bis(2-fluorobenzylidene)butane-1,4-diamine Schiff base ligand. Each Ag(I) ion is three-coordinated in a trigonal configuration by two O atoms from two benzoate anions and one N atom from a Schiff base ligand. The di-mu-benzoato-disilver(I) moieties are linked by the bridging Schiff base ligand, giving zigzag polymeric chains with an [-Ag...Ag-N-C-C-C-C-N-](n) backbone running along the b axis.
