Tris(oxamide dioxime-?N,N')nickel(II) sulfate penta-hydrate.

ABSTRACT: The asymmetric unit of the title compound, [Ni(C(2)H(6)N(4)O(2))(3)]SO(4)·5H(2)O, contains two complex cations, two sulfate anions and ten lattice water mol-ecules. In both independent cations, the central Ni(II) ion adopts a distorted octa-hedral coordination involving six imino N atoms of three bidentate oxamide dioxime ligands. The bulk structure is achieved by a three-dimensional network of O-H?O and N-H?O hydrogen bonds which inter-link the ionic partners and some water mol-ecules in such a manner that the lattice framework thus formed defines channels parallel to [100]. The other water mol-ecules are lodged inside these channels. Two of the ten water mol-ecules in the asymmetric unit are disordered over three sites, in 0.356?(3):0.324?(5):0.320?(5) and 0.247?(3):0.293?(6):0.460?(6) occupancy ratios, and one O atom of a sulfate ion is also disordered over two sites, with occupancies of 0.621?(5) and 0.379?(5).

Penta-aqua-(1H-benzimidazole-5,6-dicarboxyl-ato-κN)nickel(II) penta-hydrate.

Project description:In the title mononuclear complex, [Ni(C(9)H(4)N(2)O(4))(H(2)O)(5)]·5H(2)O, the Ni(II) atom is six-coordinated by one N atom from a 1H-benzimidazole-5,6-dicarboxyl-ate ligand and by five O atoms from five water mol-ecules and displays a distorted octa-hedral geometry. Inter-molecular O-H⋯O hydrogen-bonding inter-actions among the coordinated water mol-ecules, solvent water mol-ecules and carboxyl O atoms of the organic ligand and additional N-H⋯O hydrogen bonding lead to the formation of a three-dimensional supra-molecular network.

Bis[tris-(ethane-1,2-diamine)nickel(II)] octa-cyanidomolybdate(IV) penta-hydrate.

Project description:In the title compound, [Ni(C(2)H(8)N(2))(3)](2)[Mo(CN)(8)]·5H(2)O, the Ni(II) ion is coordinated by six N atoms from three ethane-1,2-diamine ligands in a distorted octa-hedral geometry, while the Mo(IV) atom is coordianted by eight cyanide ligands. The Ni-N bond distances range from 2.1061?(18) to 2.1425?(18)?Å. The Mo-C and C-N distances in the [Mo(CN)(8)] unit range from 2.154?(2) to 2.174?(2)?Å and 1.149?(3) to 1.156?(3)?Å, respectively. The complex ions and water mol-ecules are linked by weak N-H?N/O and O-H?N/O hydrogen bonds into a three-demensional structure.

Crystal structure of di-ammonium bis-[tris-(oxamide dioxime-κ2 N,N')nickel(II)] bis-[tris-(oxalato-κ2 O,O')chromate(III)] 6.76-hydrate.

Project description:The asymmetric unit of the title compound, (NH4)2[Ni(C2H6N4O2)3]2[Cr(C2O4)3]2·6.76H2O, comprises two NH4 + cations, two [Ni(C2H6N4O2)3]2+ cations and two [Cr(C2O4)3]3- anions, as well as eight water mol-ecules of crystallization of which only one is fully occupied. In the cationic and anionic complexes, the central atoms (NiII and CrIII) are each surrounded by three bidentate ligands (N-chelating oxamide dioxime and O-chelating oxalate, respectively), resulting in distorted octa-hedral coordination spheres. In the crystal, O-H⋯O hydrogen bonds between the oxamide dioxime ligands as donor groups and the oxalate ligands as acceptor groups alternately connect the cationic and anionic complexes into infinite pillars extending parallel to [100]. Moreover, N-H⋯O hydrogen bonds between the same ligands connect neighboring pillars, thus delineating channels that accommodate the charge-balancing NH4 + cations as well as the water mol-ecules of crystallization. Although the H atoms could not be localized for these two species, the corresponding N⋯O and O⋯O distances indicate hydrogen bonds of medium strength.

Tris(1,10-phenanthroline)nickel(II) dichromate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Ni(C(12)H(8)N(2))(3)][Cr(2)O(7)]·4H(2)O, contains one cation, one anion and four water mol-ecules, three of which are disordered over two sites with equal occupancies. In the cation, the metal centre is coordinated by six N atoms from three 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The [Cr(2)O(7)](2-) anion exhibits a staggered conformation. The crystal packing is stabilized by inter-molecular O-H?O hydrogen bonds and ?-? inter-actions, evidenced by short distances of 3.531?(5)?Å between the centroids of aromatic rings.

Project description:The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H⋯O and C-H⋯N inter-actions may help to establish the packing.

Both Ni(II) atoms in the cation and the anion lie on a mirror plane. The respective ions inter-act through Coulombic forces and through a complex network of hydrogen bonds.

Tris(propane-1,2-diamine-κN,N')nickel(II) tetra-cyanidoplatinate(II).

Project description:In the title compound, [Ni(C(3)H(10)N(2))(3)][Pt(CN)(4)], the [Pt(CN)(4)](2-) anion with the environment of the Pt(II) atom, lying on a mirror plane, is square planar, whereas the Ni(II) atom in the [Ni(C(3)N(2)H(10))(3)](2+) cation, also lying on a mirror plane, has a slightly distorted octa-hedral coordination geometry. Three chiral 1,2-diamino-propane mol-ecules, which are disordered equally over two sets of positions, adopt Δ(δδδ) and Δ(λλλ) configurations. The average Ni-N and Pt-C bond lengths are 2.131 (10) and 1.988 (10) Å, respectively. The cations and anions are connected by N-H⋯N hydrogen bonds.

Tris(1,10-phenanthroline-?N,N')nickel(II) dinitrate tetra-hydrate.

Project description:In the title complex, [Ni(C(12)H(8)N(2))(3)](NO(3))(2)·4H(2)O, the Ni(II) ion is octa-hedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O-H?O and C-H?O hydrogen bonds are present between the complex cations, nitrate anions and water mol-ecules. O-H?O hydrogen bonds between the uncoord-inated water mol-ecules lead to the formation of a four-membered ring water cluster, with a planar configuration. There were an additional five grossly disordered water mol-ecules in the asymmetric unit, which were removed by the subroutine SQUEEZE; these were were excluded in the calculation of the molecular weight, etc. ?-? stacking inter-actions between the aromatic rings are also observed [centroid-centroid distances = 3.697?(2), 3.728?(2) and 3.761?(2)?Å].
