RESUMEN
The title compound, {[Cu(C(14)H(9)NO(3))(C(5)H(5)N)].C(3)H(7)NO}n or {[Cu(2)L(2)(py)(2)].2DMF}n [py is pyridine, L is 4-(salicylideneamino)benzoate and DMF is dimethylformamide], is composed of dimeric dicopper [CuL(py)]2 building units, which are interlinked into a one-dimensional chain through the formation of Cu-O(COO) bonds. The dimeric unit is centrosymmetric, containing two Cu(II) atoms linked by bridging phenolate O atoms into a Cu(2)O(2) plane with a chelating Cu-O bond length of 1.927 (2) A and a bridging Cu-O bond length of 2.440 (2) A. Interchain C-H...O and pi-pi stacking interactions are responsible for an extensive three-dimensional structure in which the resulting channels are filled by DMF solvent molecules.
