The asymmetric unit of the title complex, [Sr 5 (C 8 H 4 O 4 ) 4 (HCO 2 ) 2 ] n , contains three independent Sr II ions, one of which is located on an inversion center. In the crystal, the Sr II ions (coordination numbers 8, 9 and 12) are connected by two crystallographically distinct benzene-1,2-dicarboxylate ligands and one formate ligand, forming a two-dimensional polymer parallel to (001).
