A novel two-dimensional layered framework built of strontium(II) with 4-nitrobenzene-1,3-dicarboxylic acid.
In poly[[aquastrontium(II)]-micro(6)-4-nitrobenzene-1,3-dicarboxylato-kappa(7)O(1):O(2):O(2):O(3):O(3),O(4):O(4)], [Sr(C(8)H(3)NO(6))(H(2)O)](n), the Sr(II) ion displays a distorted bicapped triangular prismatic configuration, defined by seven carboxyl O atoms from six symmetry-related ligands and one water molecule. The ligand molecules connect the Sr(II) ions into a two-dimensional layered framework in the ac plane, with close O...O contacts between the nitro groups and with each nitro group providing one acceptor O atom for a weak intermolecular C-H...O hydrogen bond.
