metal-organic compounds
The title complex, [Sr(C4H4O5)(H2O)3]n.nH2O, consists of polymeric zigzag chains formed by SrO9 units bridged by SrO2Sr groups along the b axis, with SrSr separations of 4.518 (1) Å. Each Sr atom is associated with three O atoms from a tridentate oxydiacetate, three O atoms from adjacent carboxylates, one monodentate and one chelating, and three O atoms from metal-bound water molecules. The chains in the crystal are linked through an extensive hydrogen-bonding system into a complex three-dimensional network.
