چکیده
The title europium(III) carboxyl-ate, [Eu(3)(C(8)H(7)O(2))(9)](n), has three independent Eu atoms, two of which are eight-coordinate in a square-anti-prismatic coordination geometry, whereas the third is nine-coordinate in a tricapped trigonal-prismatic coordination geometry. The metal atoms are linked by two bidentate and seven tridentate methyl-benzoate groups into a linear chain running along the b-axis direction.
