Diammonium aqua-(ethyl-ene-diamine-tetra-acetato)iron(II) trihydrate.

Project description:In the title compound, (NH(4))(2)[Fe(C(10)H(12)N(2)O(8))(H(2)O)]·3H(2)O, the Fe(II) center is in a distorted penta-gonal-bipyramidal geometry.

Two other carboxyl-ate O atoms from the EDTA ion occupy the apical sites. Both ammonium cations and all water mol-ecules function as hydrogen-bond donors, and ten N-H⋯O and nine O-H⋯O hydrogen bonds form a three-dimensional network between the complex anions, cations and the water mol-ecules.

catena-Poly[[aqua-(4-ethyl-benzoic acid-κO)lanthanum(III)]-tri-μ-4-ethyl-benzoato].

Project description:The reaction of lanthanum nitrate and 4-ethyl-benzoic acid (EBAH) in aqueous solution yielded the title polymer, [La(C(9)H(9)O(2))(3)(C(9)H(10)O(2))(H(2)O)](n).

Each La(III) ion is eight-coordinated by six O atoms from six bridging-bidentate EBA ligands, one O atom from a monodentate EBAH ligand and one water O atom in a distorted bicapped trigonal-prismatic geometry. The adjacent La(III) ions are linked by the carboxyl-ate groups of EBA ligands in a bridging-bidetate coordination mode, resulting in an infinite chain structure along the c axis. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules, carboxyl-ate groups and carboxyl H atoms are formed within the one-dimensional polymer. One of the ethyl groups is disordered over two positions with occupancies of 0.717 (7) and 0.283 (7).

The HEDTA ligands and some of the water mol-ecules act as bridges, linking the compound into a three-dimensional architecture via 2(1) screw, c-glide, translation and inversion symmetry operators. Meanwhile, three types of O-H⋯O hydrogen bonds provide an additional stabilization of the three-dimensional architecture.
