Description
Summary:In the title coordination polymer, {[Ba(C7H2N2O7)(H2O)2]·H2O}n, the BaII atom is ten-coordinated by seven O atoms from four 3,5-dinitrosalicylatate ligands, two μ2-bridging aqua ligands and one water molecule. The coordination mode is best described as a bicapped square-antiprismatic geometry. The 3,5-dinitrosalicylatate ligands bridge three Ba atoms. Centrosymmetrically related dinuclear barium units, with a Ba...Ba separation of 4.767 (5) Å, form infinite chains, which are further self-assembled into a supramolecular network through intermolecular O—H...O hydrogen-bonding interactions between O atoms of 3,5-dinitrosalicylatate ligands and water molecules.
