methanol produces the polymeric complex Eu(&mgr;-C(6)H(5)C(4)O(3))(2)(C(6)H(5)C(4)O(3))(2)(CH(3)OH)(2)(H(2)O)(2).(CH(3)OH)}(n)() (1) which crystallizes in the space group P2(1)/n with a = 13.4049(5) Å, b = 13.7043(7) Å, c = 18.5026(6) Å, beta = 106.351(4) degrees, and Z = 4. The Eu(III) ion is eight coordinate with two bridging and two pendant phenylsquarate ligands, the coordination polyhedron being completed
