Poly[[?-(1-ammonio-ethane-1,1-di-yl)bis-(hydrogenphospho-nato)]diaquachloridodisodium]: a powder X-ray diffraction study.

ABSTRACT: The title compound, [Na(2)(C(2)H(8)NO(6)P(2))Cl(H(2)O)(2)](n), has a polymeric two-dimensional structure extending parallel to (001). The asymmetric unit contains two Na(+) cations located on a centre of symmetry and on a mirror plane, respectively, one half of a bis-phospho-nate anion (the entire anion is completed by mirror symmetry), one chloride anion on a mirror plane and one water mol-ecule in general positions. The two Na(+) cations exhibit distorted octa-hedral NaCl(2)O(4) coordination polyhedra, each consisting of two deprotonated O atoms of the bis-phospho-nate anion, of two water mol-ecules and of two chloride anions. Strong O-H?O hydrogen bonds between the -OH group and one of the free O atoms of the bis-phospho-nate anion connect adjacent layers along [100], supported by N-H?Cl inter-actions. Intra-layer O-H?O and N-H?O hydrogen bonds are also observed.

Bis[(1-ammonio-ethane-1,1-di-yl)diphospho-nato-?O,O']diaqua-nickel(II) nona-hydrate.

Project description:The title compound, [Ni(C(2)H(8)NO(6)P(2))(2)(H(2)O)(2)]·9H(2)O, exhibits a slightly distorted octa-hedral coordination environment around the Ni(II) atom. It contains two mol-ecules of 1-amino--ethyl-idenediphospho-nic acid in the zwitterionic form, coord-inated via O atoms from two phospho-nate groups and creating two six-membered chelate rings. Two water mol-ecules in cis positions complete the coordination environment of the Ni(II) atom. The title compound contains nine partly disordered solvent water mol-ecules, which create a three-dimensional network of strong O-H?O and N-H?O hydrogen bonds.

trans-Bis[(1-ammonio-pentane-1,1-di-yl)diphospho-nato-?O,O']diaqua-copper(II).

Project description:In the title compound, [Cu(C(5)H(14)NO(6)P(2))(2)(H(2)O)(2)], the Cu(II) atom occupies a special position on an inversion centre. It exhibits a distorted octa-hedral coordination environment consisting of two O,O'-bidentate (1-ammonio-pentane-1,1-di-yl)diphospho-nate anions in the equatorial plane and two trans water mol-ecules located in axial positions. The ligand mol-ecules are coordinated to the Cu(II) atom in their zwitterionic form via two O atoms from different phospho-nate groups, creating two six-membered chelate rings with a screw-boat conformation. The CuO(6) coordination polyhedron is strongly elongated in the axial direction with 0.6?Å longer bonds than those in the equatorial plane. Intra-molecular N-H?O hydrogen bonding helps to stabilize the mol-ecular configuration. The presence of supra-molecular -PO(OH)?O(OH)P- units parallel to (100) and other O-H?O and N-H?O hydrogen bonds establish the three-dimensional set-up.

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.

catena-Poly[zinc(II)-?(3)-{hydrogen [1-hydr-oxy-2-(3-pyridinio)ethane-1,1-di-yl]diphospho-nato}].

Project description:In the polymeric title compound, [Zn(C(7)H(9)NO(7)P(2))](n), the zinc(II) centre displays a tetra-hedral coordination geometry provided by four O atoms from three different phospho-nate groups. The crystal structure consists of ladder chains parallel to the b axis built up from vertex-sharing of ZnO(4) and PO(3)C tetra-hedra. The chains are linked by strong intra- and inter-chain O-H?O and N-H?O hydrogen bonds, forming a three-dimensional supra-molecular assembly.

Diaqua-bis{[1-hydr-oxy-2-(1H-imidazol-3-ium-1-yl)ethane-1,1-di-yl]bis-(hydrogen phospho-nato)}manganese(II).

Project description:In the title compound, [Mn(C(5)H(9)N(2)O(7)P(2))(2)(H(2)O)(2)], the Mn(II) atom (site symmetry ) is coordinated by four phos-pho-n-ate O atoms from a pair of partially deprotonated 1-hydr-oxy-2-(imidazol-3-yl)ethane-1,1-bis-phophonic acid ligands (imhedpH(3) (-)) and two water mol-ecules, resulting in a slightly distorted trans-MnO(6) octa-hedral geometry for the metal ion. In the ligands, the imidazole units are protonated and two of the hydr-oxy O atoms of the phospho-nate groups are deprotonated and chelate the Mn(II), thus forming the neutral mol-ecule of the title compound. The two protonated O atoms within the phospho-nate groups of one imhedpH(3) (-) ligand act as hydrogen-bond acceptors for a bifurcated hydrogen bond originating from the coordinated water mol-ecule. The phospho-nate units of neigboring mol-ecules are connected with their equivalents in neighboring mol-ecules via two types of inversion-symmetric hydrogen-bonding arrangements with four and two strong O-H?O hydrogen bonds, respectively. The two inter-actions connect mol-ecules into infinite chains along [111] and [110], in combination forming a tightly hydrogen-bonded three-dimensional supra-molecular network. This network is further stabilized by additional hydrogen bonds between the protonated imidazole units and one of the coordinated P-O O atoms and by additional O-H?O hydrogen bonds between the water mol-ecules and the P=O O atoms of neigboring mol-ecules.

1,1'-(Ethane-1,2-di-yl)bis-(1,4,7-triazonane).

Project description:In the centrosymmetric title compound (dtne), C(14)H(32)N(6), two 1,4,7-triaza-cyclo-nonane (tacn, or 1,4,7-triazonane) moieties are linked together each at an amino position by a single ethyl-ene spacer. The mol-ecular packing is supported by pairs of inter-molecular N-H?N hydrogen bonds, which form R(2) (2)(22) ring motifs and link the mol-ecules into infinite chains running parallel to the a axis.

1,1'-(Ethane-1,2-di-yl)dipyridinium bis-(iodate).

Project description:The title salt, C(12)H(14)N(2) (2+)·2IO(3) (-), exhibits two crystallographically independent iodate anions, the I atoms of which are each in a trigonal-pyramidal environment. In the dication, the two pyridine rings adopt an anti conformation with respect to each other; the angle between these two rings is 3.84 (19)°. In the crystal structure, C-H⋯O hydrogen bonds between the cations and anions lead to the formation of layers arranged parallel to the ab plane. I⋯O halogen bonds [R(2) (2)(4) graph-set motif] range between 2.873 (2) and 3.036 (3) Å and connect neighbouring IO(3) (-) anions with each other along [100], so as to create a three-dimensional network.

1,1'-(Ethane-1,2-di-yl)bis-(indoline-2,3-dione).

Project description:The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each column are parallel; however, the mol-ecules in the two columns differ in the respective orientation of the indoline-2,3-dione fragments. In one column, they are approximately parallel to (112), while in the other they are approximately parallel to (12). The inter-planar angle between the indoline-2,3-dione fragments in the two columns is 80.83?(3)°. The mol-ecules within each column are related by mutual displacement of their centres of symmetry, that is (0, ±1/2, ±1/2). The packing between the mol-ecules is provided by weak inter-actions only, viz. C-H?O hydrogen bonds and ?-? [centroid-centroid distance = 3.8745?(8)?Å] and C=O?? inter-actions.

Hydroxonium 1-ammonio-ethane-1,1-diyl-diphospho-nate.

Project description:The title complex, H(3)O(+)·NH(3)C(CH(3))(PO(3)H)(2) (-), contains a hydroxonium ion and an NH(3)C(CH(3))(PO(3)H)(2) (-) anion. The three H atoms of H(3)O(+) form a pseudo-tetra-hedron by being distributed over four positions with occupation factors of 0.75. Multiple N-H⋯O and O-H⋯O hydrogen bonds in the crystal structure form an intricate three-dimensional supra-molecular network.
