catena-Poly[[diaqua-strontium(II)]-bis-[µ-2-(3-benzoyl-phen-yl)propano-ato]].

In the title coordination polymer, [Sr(C(16)H(13)O(3))(2)(H(2)O)(2)](n), the Sr(II) cation is eight-coordinated by six O atoms from four different 2-(3-benzoyl-phen-yl)propano-ate ligands and two O atoms of two water mol-ecules in a distorted dodeca-hedral geometry. Adjacent Sr(II) cations are bridged by two 2-(3-benzoyl-phen-yl)propano-ate ligands, forming an infinite chain along the b axis; the chains are further linked by inter-molecular O-H-O hydrogen bonds into a three-dimensional supra-molecular network.
