Redetermination of aqua-(dihydrogen ethyl-enediamine-tetra-acetato-?O,O',N,N',O'')nickel(II).

ABSTRACT: The crystal structure of the title compound, [Ni(C(10)H(14)N(2)O(8))(H(2)O)] or [Ni(H(2)edta)(H(2)O)] (H(4)edta is ethyl-ene-diamine-tetra-acetic acid), originally determined by Smith & Hoard [J. Am. Chem. Soc. (1959), 81, 556-561] has been redetermined to a significantly higher precision. The Ni(II) atom is coordinated in a distorted octa-hedral geometry by two N atoms and three O atoms from three carboxyl-ate groups of the H(2)edta(2-) ligand and by an O atom of a water mol-ecule. The complex mol-ecules are linked by inter-molecular O-H?O hydrogen bonds into layers perpendicular to [100].

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 carboxyl-ate O and two N atoms from the ethyl-enediaminetetra-acetate (EDTA) ion and one O atom from coordinated water comprise the equatorial plane. 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.

Project description:In the title complex, [Ni(C(8)H(5)Cl(2)O(3))(2)(H(2)O)(4)], the Ni(II) atom (site symmetry ) adopts a slightly distorted NiO(6) octa-hedral coordination.

Project description:In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], the Ni(II) atom, located on a centre of inversion, is coordinated by two N atoms from two 2-(4-pyridyl-sulfan-yl)acetate ligands and four water O atoms in an octa-hedral geometry. In the crystal, inter-molecular O-H?O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate group of the anionic 2-(4-pyridyl-sulfan-yl)acetate ligands link these discrete mononuclear units into a three-dimensional network.

Project description:In the title compound, [Ni(C8H6ClO3)2(H2O)4], the Ni(II) ion is located on a crystallographic inversion centre and is octa-hedrally coordinated by two 2-(4-chloro-phen-oxy)acetate ligands in axial positions and by four water mol-ecules in the equatorial plane. The acetate ligands are bound to the Ni(II) ion in a monodentate manner through a carboxyl-ate O atom. In the crystal, O-H?O hydrogen bonds link the mol-ecules, forming a two-dimensional supra-molecular network lying parallel to the ab plane.

Tetra-pyridine-bis(trichloro-acetato)nickel(II).

Project description:The title compound, [Ni(C(2)Cl(3)O(2))(2)(C(5)H(5)N)(4)], was prepared by the reaction of pyridine and trichloro-acetatonickel(II) in ethanol solution at room temperature. The Ni(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination made up of four N atoms of the pyridine ligands and two O atoms of trichloro-acetate anions. The mol-ecular structure and packing are stabilized by intra- and inter-molecular C-H?O hydrogen-bonding inter-actions.

?-Pyrazine-bis-[tetra-aqua-cadmium(II)] ?-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H?O inter-actions.

Project description:The reaction of ZnO and tri-ethyl-ene-tetra-minehexaacetic acid (H6TTHA) in aqueous solution after refluxing yields the binuclear title compound, [Zn2(C18H26N4O12)(H2O)2]·4H2O. There is a centre of symmetry in the [Zn2(H2TTHA)(H2O)2] mol-ecule in the crystalline state. Both Zn(II) ions are octahedrally surrounded and bound by an N2O3 donor set from the H2TTHA(4-) anion and a water mol-ecule; the N atoms are cis and the water mol-ecule is trans to an N atom. The Zn?Zn separation is 7.562?(1)?Å. An intra-molecular C-H?O inter-action is observed and both carboxyl-ate H atoms are disordered over two adjacent sites. In the crystal, the components are linked by O-H?O and C-H?O hydrogen bonds generating a three-dimensonal network.
