Tetra-aqua-bis[(1-ammonio-1-phosphono-ethyl)phospho-nato]zinc(II) tetra-hydrate.

ABSTRACT: The title compound, [Zn(C(2)H(8)NO(6)P(2))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the reaction of ZnCl(2) with 1-amino-ethane-1,1-diyldiphospho-nic acid in aqueous solution. The asymmetric unit contains one-half of the complex and two water mol-ecules of solvation. The Zn atom occupies a special position on an inversion centre. This results in a slightly distorted octa-hedral coordination environment, which consists of the O atoms from two phospho-nic acids and four water mol-ecules. The crystal structure displays N-H?O and O-H?O hydrogen bonding, which creates a three-dimensional network.

Crystal structure of bis-[(1-ammonio-1-phosphono-eth-yl)phospho-nato]tetra-aqua-cadmium dihydrate: a powder X-ray diffraction study.

Project description:In the title compound, [CdL 2(H2O)4]·2H2O [L = (1-ammonio-1-phosphono-eth-yl)phospho-nate, C2H8NO6P2 (-)], the Cd(II) ion is situated on an inversion centre being coordinated by four aqua mol-ecules in the equatorial plane and two phosphonate O atoms from two deprotonated L ligands in the axial positions in a distorted octa-hedral geometry. The asymmetric unit contains one-half of the complex mol-ecule and one lattice water mol-ecule. The ligand L exists in a zwitterionic form, with a positive charge on the NH3 group and a negative charge on the O atom of the non-coordinating phospho-nate group, and with an intra-molecular O-H⋯O inter-action forming an S(6) ring motif and two intra-molecular N-H⋯O inter-actions each generating an S(5) ring motif. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the complex mol-ecules into a three-dimensional network in which the voids of 38 Å(3) are filled with ordered lattice water mol-ecules, which are also involved in O-H⋯O hydrogen bonding.

Crystal structure of di-?-hydroxido-bis-{aqua-[ethyl (1,10-phenanthrolin-3-yl)phospho-nato-?2 N,N']copper(II)} hepta-hydrate.

Project description:In the title compound, [Cu2(OH)2{C12H7N2(PO3C2H5)}2(H2O)2]·7H2O, two Cu2+ cations are bridged by two hydroxide groups, forming a centrosymmetric binuclear complex. Each Cu2+cation is further coordinated by the N atoms of a bidentate ethyl (1,10-phenanthrolin-3-yl)phospho-nate anion and a water mol-ecule in a square-pyramidal geometry. In the crystal, a network of O-H?O hydrogen bonds involving the P(O)(O-)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water mol-ecules generates a three-dimensional supra-molecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

Tetra-aqua-bis-[5-(3-pyrid-yl)tetra-zolido-?N]zinc(II) tetra-hydrate.

Project description:The title compound, [Zn(C(6)H(4)N(5))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the hydro-thermal reaction of Zn(CH(3)COO)(2)·2H(2)O with 3-(2H-tetra-zol-5-yl)pyridine. The Zn(II) ion is located on an inversion center and is coordinated by two pyridine N atoms from two 5-(3-pyrid-yl)tetra-zolide ligands and four coordinated water mol-ecules in a slightly distorted octa-hedral geometry. The dihedral angle between the pyridine and tetra-zole rings is 9.920?(7)°. In the crystal, mol-ecules are linked into a three-dimensional network by inter-molecular O-H?O and O-H?N hydrogen bonds involving the tetra-zole group N atoms, the aqua ligands and solvent water mol-ecules.

trans-Tetra-aqua-bis-(isonicotinamide-κN (1))zinc bis-(3-hy-droxy-benzoate) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Zn(C6H6N2O)2(H2O)4](C7H5O3)2·4H2O, contains half of the complex cation with the Zn(II) ion located on an inversion center, a 3-hy-droxy-benzoate counter-anion and two uncoordinating water mol-ecules. Four water O atoms in the equatorial plane around the Zn(II) ion [Zn-O = 2.089 (2) and 2.128 (2) Å] form a slightly distorted square-planar arrangement and the distorted octa-hedral geometry is completed by the two N atoms [Zn-N = 2.117 (2) Å] from two isonicotinamide ligands. In the anion, the carboxyl-ate group is twisted from the attached benzene ring at 9.0 (2)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O-H⋯O and N-H⋯O and weak C-H⋯O hydrogen bonds, consolidates the crystal packing, which exhibits π-π stacking between the benzene and pyridine rings, with centroid-centroid distances of 3.458 (2) and 3.609 (2) Å. One of the two H atoms of each uncoordinating water mol-ecule is disordered over two orientations with an occupancy ratio of 0.60:0.40.

Tetra-aqua-bis(2-methyl-benzimidazolium-1,3-diacetato-κO)zinc(II) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Zn(C(12)H(11)N(2)O(4))(2)(H(2)O)(4)]·4H(2)O, contains one-half of the complex mol-ecule and two uncoordin-ated water mol-ecules. The four water O atoms in the equatorial plane around the Zn(II) centre ( symmetry) form a distorted square-planar arrangement, while the distorted octa-hedral coordination geometry is completed by the O atoms of the zwitterionic 2-methyl-benzimidazolium-1,3-diacetate ligands in the axial positions. The benzimidazole ring system is planar, with a maximum deviation of 0.041 (3) Å. Intra-molecular O-H⋯O hydrogen bonding results in the formation of a non-planar six-membered ring. In the crystal structure, strong intra- and inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between benzimidazole rings [centroid-centroid distance = 3.899 (1) Å] may further stabilize the structure.

catena-Poly[[[tetra-aqua-magnesium]-trans-?-[(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nato] hemihydrate].

Project description:The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of the corners of the MgO6 polyhedra and bind to the O atoms of the phospho-nate groups of neighbouring chains. The lattice water molecule is disordered around an inversion centre, exhibiting an occupancy of 0.25.
