Diaqua-bis-(dihydrogen 3-aza-niumyl-1-hy-droxy-propyl-idene-1,1-di-phos-phon-ato-?O,O')cobalt(II).

ABSTRACT: The asymmetric unit of title compound, [Co(C(3)H(10)NO(7)P(2))(2)(H(2)O)(2)], contains one half-mol-ecule of the complex. The Co(II) atom is located on an inversion centre and displays a distorted octa-hedral coordination geometry defined by four O atoms of two 3-aza-niumyl-1-hy-droxy-propyl-idene-1,1-bis-phospho-nato ligands in the equatorial plane and two water mol-ecules located in axial positions. The ligand mol-ecules, which exist in a zwitterionic state, form two six-membered chelate rings with chair conformations. In the crystal, mol-ecules are inter-linked by O-H?O and N-H?O hydrogen bonds, forming a three-dimensional supra-molecular structure.

Project description:The crystal structure of the title compound, {[Er(2)(C(2)H(4)O(6)PS)(OH)(3)(H(2)O)]·H(2)O}(n), consists of two Er(3+) ions, one (C(2)H(4)O(6)PS)(3-) ion, three OH(-) ions, and two water mol-ecule. The Er(3+) ions form ErO(8) polyhedra., which are connected by ?- and ?(3)-O atoms. Thus, inorganic Er-O-Er layers of edge- and face-sharing polyhedra are observed. Whereas most often in metal phosphono-sulfonates the organic linker bridges adjacent layers, in the title compound, the (O(3)PC(2)H(4)SO(3))(3-) anion is only connected to one Er-O-Er layer. Short interatomic O?O distances [2.898?(8), 2.997?(14) and 2.768?(10)?Å] indicate hydrogen bonding between the layers. The noncoordinated water mol-ecules are located between the layers.

Poly[[hexa-?-aqua-diaqua-bis-(??-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa?(C??H?O?)?(H?O)?]·2H?O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by ??-bridging btec ligands, which form inter-molecular O-H?O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H?O hydrogen bonds.

Poly[[{?(3)-dihydrogen [(pyridin-4-yl-methyl-imino)-bis-(methyl-ene)]diphos-phon-ato-?O:O',N,O'':N'}copper(II)] dihydrate].

Project description:In the title polymer, {[Cu(C(8)H(12)N(2)O(6)P(2))]·2H(2)O}(n), the geometry of the five-coordinate Cu(II) ion can best be described as slightly distorted square-pyramidal formed by one N and two O atoms of an N(CH(2)PO(3)H)(2) group and one N atom from a pyridine ring. The elongated apex of the pyramid is occupied by one O atom from a third diphospho-nate ligand. The inter-connection of Cu(2+) ions by the diphospho-nate ligands results in the formation of a double-chain array along the b axis, in which the two sub-chains are inter-locked by pairs of PO(3) groups. The outside of each sub-chain is decorated by other PO(3) groups. These double chains are further assembled into a three-dimensional supra-molecular architecture via a large number of O-H?O hydrogen bonds between the phospho-nate groups and lattice water mol-ecules.

(1RS,2RS)-4,4'-(1-Aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium tetra-chlorido-platinate(II) chloride.

Project description:The title compound, (C12H16N3O)[PtCl4]Cl, consists of a 4,4'-(1-aza-niumyl-2-hy-droxy-ethane-1,2-di-yl)dipyridinium trication, a square-planar tetra-chloridoplatinate(II) dianion and a chloride ion. In the cation, the pyridinium rings attached to the central 1-aza-niumyl-2-hy-droxy-ethane fragment have an anti conformation, as indicated by the central C-C-C-C torsion angle of -166.5?(6)°, and they are inclined to one another by 63.5?(4)°. In the crystal, the cations and anions are linked through N-H?Cl and O-H?Cl hydrogen bonds. There are also ?-? contacts [centroid-centroid distances = 3.671?(4) and 3.851?(4)?Å] and a number of C-H?Cl inter-actions present, consolidating the formation of a three-dimensional supra-molecular structure.

1-Aza-niumyl-cyclo-butane-1-carboxyl-ate monohydrate.

Project description:In the title compound, C5H9NO2·H2O, the amino acid is in the usual zwitterionic form involving the ?-carboxyl-ate group.
