N2 - Four strontium(II) salts with organic acids have been studied. Poly[diaquadi--ibuprofenato-strontium(II)] or poly[diaquabis[-2-(4-isobutylphenyl)propionato]strontium(II)], [Sr(C13H17O2)2(H2O)2]n, crystallizes with eight-coordinated Sr atoms. The coordination polyhedra are interconnected by edge-sharing to form chains. The Sr coordination chains are packed into layers, which are stacked by van der Waals interactions. Poly[-aqua-diaquadi--malonato-distrontium(II)], [Sr2(C3H2O4)2(H2O)3]n, crystallizes with nine-coordinated Sr atoms three-dimensionally interconnected into a framework structure. One of the two crystallographically independent water molecules is located on a twofold axial site. catena-Poly[[diaqua(ascorbato)strontium(II)]--ascorbato], [Sr(C6H7O6)2(H2O)2]n, crystallizes with isolated eight-coordinated Sr polyhedra. One of the ascorbate ligands bridges two Sr atoms, forming zigzag polyhedral ascorbate chains. These chains are tied together by a three-dimensional hydrogen-bonding network. Poly[aqua--2-oxidobenzoato-strontium(II)], [Sr(C7H4O3)(H2O)]n, crystallizes with eight-coordinated Sr atoms. The polyhedra are interconnected by face- and edge-sharing into layers. These layers are stacked by van der Waals forces between the protruding 2-oxidobenzoate ligands.
