Catena-Poly[[[diaqua-(tetra-methyl-ethylenediamine-?(2) N,N')nickel(II)]-?-sulfato-?(2) O:O'] monohydrate].

ABSTRACT: The title compound, {[Ni(SO4)(C6H16N2)(H2O)2]·H2O} n , contains a Ni(II) atom that is coordinated nearly octa-hedrally by a chelating tetra-ethyl-enediamine (tmeda) ligand, two water mol-ecules in a cis arrangement and two O atoms of two sulfate anions in a trans arrangement. The sulfate anions act as ?2-bridging ligands leading to a chain structure of alternating NiO4N2 octa-hedra and SO4 tetra-hedra parallel to [001]. The polymeric chains are linked by O-H?O hydrogen bonds between coordinating water mol-ecules and sulfate anions to give double strands. There is a lattice water mol-ecule which is also involved in O-H?O hydrogen bonding between adjacent [Ni(SO4)(tmeda)(H2O)2] chains.

catena-Poly[[diaqua-bis-(3-methyl-pyridine-?N)cobalt(II)]-?-sulfato-?O:O'].

Project description:The environment of the Co(II) ion in the title compound, [Co(SO(4))(C(6)H(7)N)(2)(H(2)O)(2)](n), exhibits an octa-hedral configuration with the two 3-methyl-pyridine ligands lying in cis positions with respect to each other and trans to the two coordinated water mol-ecules. The axial positions are occupied by O atoms of the sulfate ions. Co and S atoms occupy special positions (twofold axis, Wyckoff position 4c). Neighboring Co(II) ions are covalently connected with each other through the sulfate ions, thus creating infinite polymeric chains that run along the c axis. The water mol-ecules are connected with neighboring sulfate ions through strong O-H?O hydrogen bonds. Intra-molecular hydrogen bonds parallel to the propagation direction of the chains stabilize the polymeric chains, and inter-molecular hydrogen bonds between chains connect neighboring chains with each other, thus leading to polymeric double chains.

Lithium diaqua-nickel(II) catena-borodiphosphate(V) monohydrate.

Project description:The title borophosphate LiNi(H(2)O)(2)[BP(2)O(8)]·H(2)O was synthesized under hydro-thermal conditions. The crystal structure is isotypic with the Mg analogue and features helical [BP(2)O(8)](3-) borophosphate ribbons, constructed by BO(4) (2 symmetry) and PO(4) tetra-hedra. The borate groups share all their oxygen apices with adjacent phosphate tetra-hedra. The ribbons are connected via Ni(2+) cations that are located on twofold rotation axes. The cations have a slightly distorted octa-hedral oxygen coordination by four O atoms from the anion and by two water mol-ecules. The voids within the helices are occupied by Li(+) cations, likewise located on twofold rotation axes, in an irregular environment of five O atoms. The structure is stabilized by O-H?O hydrogen bonds between coordinated or uncoordinated water mol-ecules and O atoms that are part of the helices.

catena-Poly[[[diaqua-copper(II)]-{?-4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoato}] monohydrate].

Project description:The asymmetric unit of the title polymeric compound, {[Cu(C(22)H(18)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoate ligand, a coordin-ated water mol-ecule in a general position and an uncoordin-ated water mol-ecule situated on a twofold rotation axis. The distorted octa-hedral coordination geometry of the Cu(II) ion is formed by six O atoms. The -NH- groups of the ligand are involved in intra-molecular N-H?O hydrogen bonds, while the water mol-ecules participate in the formation of a three-dimensional supra-molecular framework via inter-molecular O-H?O hydrogen bonds.

catena-Poly[[[diaqua-nickel(II)]-di-?-glycine] dichloride].

Project description:In the polymeric title complex, {[Ni(C(2)H(5)NO(2))(2)(H(2)O)(2)]Cl(2)}(n), the Ni(II) atom lies on an inversion center and is in a distorted octa-hedral NiO(6) configuration, with four carboxyl-ate O atoms from four zwitterionic glycine mol-ecules forming the equatorial plane and two water O atoms occupying the axial positions. The Cl(-) counterions lie in the inter-stices. The Ni(II) complexes are linked into polymeric sheets parallel to the bc plane. These sheets are then further connected into a three-dimensional network by O-H?O, O-H?Cl and N-H?Cl hydrogen bonds, together with weak C-H?O inter-actions.

catena-Poly[[[diaqua-(di-2-pyridylamine-?N,N')nickel(II)]-?-fumarato-?O:O] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Ni(C(4)H(2)O(4))(C(10)H(9)N(3))(H(2)O)(2)]·4H(2)O}(n), zigzag chains are built up from cis-[Ni(dpya)(H(2)O)(2)](2+) cations (dpya is di-2-pyridylamine) linked by bis-monodentate coordinated bridging fumarate ligands. The Ni(II) atom is coordinated by one chelating dpya ligand, two aqua ligands in trans positions and two monodentate fumarate ligands in cis positions in the form of a deformed octa-hedron. The water mol-ecules, O atoms of the fumarate carboxyl-ate groups and the amine group of the dpya ligand are involved in an extended network of intra- and inter-molecular O-H?O hydrogen bonds. Moreover, ?-? inter-actions between the pyridine rings of the dpya ligand contribute to the stability of the structure. Two of the five uncoordinated water molecules are half-occupied.

catena-Poly[[diaqua-(1H-imidazo[4,5-f][1,10]phenanthroline)cobalt(II)]-?-sulfato].

Project description:The Co(II) ion in the title complex, [Co(SO(4))(C(13)H(8)N(4))(H(2)O)(2)](n), has a slightly distorted octa-hedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water mol-ecules. The bridging sulfate ligands connect Co(II) ions to form a one-dimensional chain along the b-axis direction. In the crystal structure, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link the chains into a three-dimensional network.

catena-Poly[[triaqua-(pyridine-κN)nickel(II)]-μ-sulfato-κO:O'].

Project description:The title compound, [Ni(SO(4))(C(5)H(5)N)(H(2)O)(3)](n), was synthesized by the hydro-thermal reaction of NiSO(4)·6H(2)O, pyridine and water. The central Ni(II) atom is coordinated in a distorted octa-hedral environment by a pyridine N atom, three aqua O atoms and two O atoms of bridging sulfate anions, yielding a zigzag chain. A three-dimensional network is generated via complex hydrogen bonds involving the sulfate and aqua ligands and a pyridine C-H group.

catena-Poly[[[tetra-kis-(4-methyl-pyridine-κN)copper(II)]-μ-sulfato-κO:O'] 4.393-hydrate].

Project description:The structure of the title compound, {[Cu(SO(4))(C(6)H(7)N)(4)]·4.393H(2)O}(n), consists of Cu(2+) ions surrounded in a square-planar fashion by 4-methyl-pyridine ligands, forming two crystallographically independent Cu{H(3)C(C(5)H(4)N)}(4) units that are both located on crystallographic inversion centers. The Cu(4-methyl-pyridine)(4) units are, in turn, connected with each other via bridging sulfate anions, leading to the formation of infinite [Cu{H(3)C(C(5)H(4)N)}(4)SO(4)](n) zigzag chains along [001]. The completed coordination spheres of the Cu(2+) ions are slightly distorted octa-hedral. The axial Cu-O bonds are elongated [average length = 2.42 (4) Å] compared to the equatorial Cu-N bonds [average length = 2.043 (2) Å]. The inter-stitial space between the chains is filled with uncoordinated water mol-ecules that consolidate the structure through O-H⋯O hydrogen bonding. One of the five crystallographically independent solvent water mol-ecules is partially occupied with an occupancy factor of 0.396 (4). Due to hydrogen bonding between symmetry-equivalent water mol-ecules across inversion centers, several of the water H atoms are disordered in 1:1 ratios over mutually exclusive positions. The crystal under investigation was found to be non-merohedrally twinned in a 0.789 (1):0.211 (1) ratio by a 180° rotation around the reciprocal b axis.

Project description:In the title complex, [Zn(C(15)H(10)O(6))(H(2)O)(2)](n), the Zn(II) atom is located on a twofold rotation axis and exhibits a distorted tetrahedral coordination environment defined by two O atoms from two 4,4'-(methyl-enedioxy)-dibenzoate ligands and two O atoms from two coordinated water mol-ecules. In the crystal structure, mol-ecules are linked into a three-dimensional framework by O-H?O hydrogen bonds and C-H?? inter-actions.

Project description:In the title complex, [Ni(C(16)H(36)N(4))(H(2)O)(2)][Ni(CN)(4)], the [Ni(teta)(H(2)O)(2)](2+) cations (teta = 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-ne) and [Ni(CN)(4)](2-) anions are arranged in an alternating fashion through electrostatic and N-H?N and O-H?N hydrogen-bonding inter-actions, forming a two-dimensional layered structure. Adjacent layers are linked through weak van der Waals inter-actions, resulting in a three-dimensional supra-molecular network.
