Bis(4-amino-pyridinium) hexa-aqua-nickel(II) bis-(sulfate).

ABSTRACT: In the title compound, (C5H7N2)2[Ni(H2O)6](SO4)2, the Ni(II) cation is located on an inversion centre and is coordinated by six aqua ligands in a slightly distorted octa-hedral coordination environment. The [Ni(H2O)6](2+) ions are connected through an extensive network of O-H?O hydrogen bonds to sulfate anions, leading to the formation of layers parallel to (001). The 4-amino-pyridinium cations are located between these layers and are connected to the anionic framework by N-H?O hydrogen bonds. Weak ?-? inter-actions between the pyridine rings, with a centroid-centroid distance of 3.754?(9)?Å, provide additional stability to the crystal packing.

Dipotassium hexa-aqua-nickel(II) bis-[hexa-fluoridozirconate(IV)].

Project description:Single crystals of the title compound, K(2)[Ni(H(2)O)(6)][ZrF(6)](2), were grown by slow evaporation of a 40% aqueous HF solution in which a stoichiometric mixture of NiCl(2)·6H(2)O, ZrF(4) and KCl was dissolved. The monoclinic structure is isotypic with its K(2)Cu, K(2)Zn, Cs(2)Zn and Cs(2)Cu analogues. The structure is built up from isolated, slightly elongated octa-hedral [Ni(H(2)O)(6)](2+) complex cations (symmetry ) and dimeric [Zr(2)F(12)](4-) complex anions (symmetry ) that are also isolated from each other. The [Zr(2)F(12)](4-) anion results from the association of two distorted penta-gonal-bipyramidal [ZrF(7)] coordination polyhedra by sharing an equatorial edge passing through an inversion center of the unit cell. Both isolated [Ni(H(2)O)(6)](2+) and [Zr(2)F(12)](4-) complex ions are situated in planes parallel to (010). They are connected by the eight-coordinated K(+) ions into a three-dimensional structure. An intricate O-H?F hydrogen-bonding network consolidates the structure.

2,2'-Biimidazolium hexa-aqua-manganese(II) bis-(sulfate).

Project description:The title compound, (C(6)H(8)N(4))[Mn(H(2)O)(6)](SO(4))(2), was obtained by cocrystallization of 2,2'-biimidazolium sulfate and bis-(tetra-butyl-ammonium) tetra-chlorido-manganate(II). The asymmetric unit contains one isolated (SO(4))(2-) anion, one half of an octa-hedral [Mn(H(2)O)(6)](2+) dication and one half of a 2,2'-biimidazolium dication, each of which lies on an inversion centre. Mol-ecules are connected by a three-dimensional N-H⋯O and O-H⋯O hydrogen-bond network.

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-nickel(II) bis-(sulfate) dihydrate.

Project description:In the title salt, (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O, the Ni(II) cation is located on a centre of inversion and exhibits a slightly distorted octa-hedral arrangement of water mol-ecules. The Ni-O bond lengths in the complex [Ni(H2O)6](2+) cation show a distribution as in the related Tutton salt (NH4)2[Ni(H2O)6](SO4)2, but are longer in average [2.056?(13) versus 2.037?(12)?Å]. The noncoordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate and [Ni(H2O)6](2+) octa-hedra via O-H?O and N-H?O hydrogen bonds from weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel (001).

catena-Poly[bis-(4-amino-pyridinium) [[tetra-aqua-nickel(II)]-?-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-cobalt(II) bis-(sulfate) dihydrate.

Project description:The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093 (17) Å], but are significantly longer than in the isotypic Ni(II) compound (Δd ≃ 0.04 Å). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454 (4) to 1.470 (3) Å [mean 1.465 (12) Å]; however, the O-S-O angles vary clearly from 108.1 (2) to 110.2 (2)° [average bond angle 109.5 (9)°]. The non-coordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate tetrahedra and the [Co(H2O)6](2+) octa-hedron via O-H⋯O and N-H⋯O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).

Bis(dimethyl-malonato-κO,O')bis-[4-(4-pyridylamino-κN)pyridinium]nickel(II) hexa-hydrate.

Project description:In the title compound, [Ni(C(5)H(6)O(4))(2)(C(10)H(10)N(3))(2)]·6H(2)O, divalent nickel ions situated on the crystallographic twofold axis are octa-hedrally coordinated by four O atoms from two dimethyl-malonate ligands in a 1,3-chelating mode and two N atoms from two protonated monodentate 4,4'-dipyridylamine mol-ecules. The mol-ecules link into chains via N-H⋯O hydrogen bonding mediated by protonated pyridyl groups. The chains form layer patterns via π-π stacking [centroid-centroid distance = 3.777 (2) Å] . Water mol-ecule hexa-mers are generated from the unligated water mol-ecules (three per asymmetric unit) by inversion centers at Wyckoff position d. These clusters are situated between the pseudolayers, providing hydrogen-bonding pathways that build up the three-dimensional structure.

Tetra-aqua-bis[4-(methyl-amino)benzoato-?O]nickel(II).

Project description:The title complex, [Ni(C(8)H(8)NO(2))(2)(H(2)O)(4)], is centrosymmetric with the Ni(II) ion located on a centre of symmetry. It contains two 4-(methyl-amino)benzoate (PMAB) anions and four coordinated water mol-ecules. The four O atoms in the equatorial plane around the Ni(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by two O atoms of the PMAB anions in the axial positions. In the crystal structure, inter-molecular O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Hexa-aqua-zinc(II) dinitrate bis-[5-(pyridinium-3-yl)tetra-zol-1-ide].

Project description:Hexa-aqua-zinc(II) dinitrate 5-(pyridinium-3-yl)tetra-zol-1-ide, [Zn(H2O)6](NO3)2·2C6H5N5, crystallizes in the space group P . The asymmetric unit contains one zwitterionic 5-(pyridinium-3-yl)tetra-zol-1-ide mol-ecule, one NO3- anion and one half of a [Zn(H2O)6]2+ cation ( symmetry). The pyridinium and tetra-zolide rings in the zwitterion are nearly coplanar, with a dihedral angle of 5.4 (2)°. Several O-H⋯N and N-H⋯O hydrogen-bonding inter-actions exist between the [Zn(H2O)6]2+ cation and the N atoms of the tetra-zolide ring, and between the nitrate anions and the N-H groups of the pyridinium ring, respectively, giving rise to a three-dimensional network. The 5-(pyridinium-3-yl)tetra-zol-1-ide mol-ecules show parallel-displaced π-π stacking inter-actions; the centroid-centroid distance between adjacent tetra-zolide rings is 3.6298 (6) Å and that between the pyridinium and tetra-zolide rings is 3.6120 (5) Å.

Bis(4-amino-pyridinium) sulfate monohydrate.

Project description:The asymmetric unit of the title compound, 2C(5)H(7)N(2) (+)·SO(4) (2-)·H(2)O, contains two 4-amino-pyridinium cations (A and B), a sulfate dianion and a water mol-ecule. One of the 4-amino-pyridinium cations (B) is disordered over two orientations with refined site occupancies of 0.568 (4) and 0.432 (4). The non-H atoms of the 4-amino-pyridinium cations are essentially coplanar, with a maximum deviation of 0.055 (1) Å (in cation A), 0.022 (3) Å (for the major component in cation B) and 0.009 (3) Å (for the minor component in cation B). In the crystal, the sulfate O atoms link the 4-amino-pyridinium cations and water mol-ecules into a three-dimensional network via inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. The crystal structure is further consolidated by N-H⋯O(water) and C-H⋯O(water) hydrogen bonds.
