title: catena-Poly[bis-(μ-4-methyl-benzoato-κO:O')hepta-kis(μ-4-methyl-benzoato-κO,O':O)tris-amarium(III)].
abstract: The title samarium coordination polymer, [Sm(3)(C(8)H(7)O(2))(9)](n), was obtained by the hydro-thermal reaction of Sm(NO(3))(3) with 4-methyl-benzoic acid in alkaline aqueous solution. In the asymmetric unit, there are three crystallographically independent Sm(III) ions, two of which are eight-coordinate in a distorted square-anti-prismatic environment, while the third is nine-coordinate in a distorted tricapped trigonal-prismatic coordination. The metal centres are coordinated and bridged by four tridentate, three bidentate and two monodentate methyl-benzoate anions, forming polymeric chains running parallel to the b axis.
