Crystal structure of a new tripotassium hexa-nickel iron hexa-phosphate.

ABSTRACT: A new potassium-nickel iron phosphate, K3Ni6Fe(PO4)6, has been synthesized by solid-state reaction and structurally characterized by single-crystal X-ray diffraction and qualitative energy dispersive X-ray spectroscopy (EDS) analysis. The structure is built up by [FeO6], [PO4], and [NiO6] coordination polyhedra, which are linked to each other by edge and corner sharing to form zigzag layers parallel to the ab plane. These layers are inter-connected by [PO4] tetra-hedra and [NiO6] octa-hedra via common corners, leading to a three-dimensional framework delimiting large channels running along the [100] direction in which the K+ cations are localized.

Crystal structure of di-chlorido-(4,11-dimethyl-1,4,8,11-tetra-aza-bicyclo-[6.6.2]hexa-deca-ne)iron(III) hexa-fluorido-phosphate.

Project description:The title compound, [FeCl2(C14H30N4)]PF6, contains Fe(3+) coordinated by the four nitro-gen atoms of an ethyl-ene cross-bridged cyclam macrocycle and two cis chloride ligands in a distorted octa-hedral environment. In contrast to other similar compounds this is a monomer. Inter-molecular C-H?Cl inter-actions exist in the structure between the complex ions. Comparison with the mononuclear Fe(2+) complex of the same ligand shows that the smaller Fe(3+) ion is more fully engulfed by the cavity of the bicyclic ligand. Comparison with the ?-oxido dinuclear complex of an unsubstituted ligand of the same size demonstrates that the methyl groups of 4,11-dimethyl-1,4,8,11-tetra-aza-bicyclo-[6.6.2]hexa-decane prevent dimerization upon oxidation.

In the crystal, C-H?F inter-actions connect the cation and anion pairs into a three-dimensional network. Weak ?-? inter-actions are observed between the imidazolium ring and the aromatic benzene ring of an adjacent mol-ecule with C?C and C?N distances ranging from 3.3714?(16) to 3.4389?(15)?Å.

The crystal structure of a new polymorph of hexa-aqua-nickel(II) bis-(6-oxo-1,6-di-hydro-pyridine-3-carboxyl-ate).

Project description:In a new polymorph of the title salt, [Ni(H2O)6](C6H4NO3)2, the metal atom of the cationic complex lies on a symmetry centre and is coordinated by six water mol-ecules to provide a quite regular octa-hedral coordination environment. These cations inter-act with 6-oxo-1,6-di-hydro-pyridine-3-carboxyl-ate anions through electrostatic inter-actions and by means of O-H?O and N-H?O hydrogen bonds involving the carboxyl-ate, keto and protonated imine groups of the anion, and the coordinating water mol-ecules from the cationic complex entity to generate a supra-molecular three-dimensional architecture. The previously reported polymorph of this compound presents a network of hydrogen bonds, in which the organic anions establish mutual hydrogen-bonding inter-actions involving their keto and protonated imine groups.

Crystal structure of (3-carb-oxy-prop-yl)tri-phenyl-phospho-nium hexa-fluorido-phosphate.

Project description:In the title mol-ecular salt, C22H22O2P(+)·PF6 (-), the side chain of the cation adopts an anti-gauche conformation [P-C-C-C and C-C-C-C torsion angles = -179.11?(10) and -77.18?(16)°, respectively]. In the crystal, the cations are linked into carb-oxy-lic acid inversion dimers by pairs of O-H?O hydrogen bonds. Weak C-H?F and C-H?(F,F) hydrogen bonds connect the components into a three-dimensional network, but there are no aromatic ?-? stacking inter-actions.

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).

Crystal structure of [3,10-bis-(4-fluoro-pheneth-yl)-1,3,5,8,10,12-hexa-aza-cyclo-tetra-deca-ne]nickel(II) diperchlorate.

Project description:The square-planar nickel(II) title complex, [Ni(C24H36F2N6)](ClO4)2 or [NiL](ClO4)2 (L = 3,10-bis-(4-fluoro-pheneth-yl)-1,3,5,8,10,12-hexa-aza-cyclo-tetra-deca-ne) was synthesized by a one-pot reaction of template condensation and its X-ray crystal structure was determined. The nickel(II) ion lies close by a twofold axis and the complex displays whole-mol-ecule disorder. Ligand L, a hexa-aza-cyclo-tetra-decane ring having 4-fluoro-phenethyl side chains attached to uncoordinated nitro-gen atoms, adopts a trans III (R,R,S,S) configuration. The average Ni-N bond distance is 1.934 (9) Å, which is quite similar to those of other nickel(II) complexes with similar ligands. The nickel(II) ion is located 0.051 (7) Å above the least-squares plane through the four coordinated N atoms. The average C-N bond distance and C-N-C angle involving uncoordinated nitro-gen atoms are 1.425 (12) Å and 118.0 (9)°, respectively, indicating a significant contribution of sp 2 hybridization for these N atoms. The inter-molecular N-H⋯O, C-H⋯O/F hydrogen bonds of the complex form a network structure, which looks like a seamless floral lace pattern.

Crystal structure of hydrazine iron(III) phosphate, the first transition metal phosphate containing hydrazine.

Project description:The title compound, poly[(?2-hydrazine)(?4-phosphato)iron(III)], [Fe(PO4)(N2H4)] n , was prepared under hydro-thermal conditions. Its asymmetric unit contains one Fe(III) atom located on an inversion centre, one P atom located on a twofold rotation axis, and two O, one N and two H atoms located on general positions. The Fe(III) atom is bound to four O atoms of symmetry-related PO4 tetra-hedra and to two N atoms of two symmetry-related hydrazine ligands, resulting in a slightly distorted FeO4N2 octa-hedron. The crystal structure consists of a three-dimensional hydrazine/iron phoshate framework whereby each PO4 tetra-hedron bridges four Fe(III) atoms and each hydrazine ligand bridges two Fe(III) atoms. The H atoms of the hydrazine ligands are also involved in moderate N-H?O hydrogen bonding with phosphate O atoms. The crystal structure is isotypic with the sulfates [Co(SO4)(N2H4)] and [Mn(SO4)(N2H4)].

Synthesis and crystal structure of a new chiral α-aminooxime nickel(II) complex

Project description:The reaction of a nickel precursor with an enantiomerically pure amino-oxime issued from (R)-limonene led to the formation of bis[κ3N,N,N-(aminooxime)-μ-chlorido]dichlorodinickel as a new dinuclear nickel complex. A dinuclear nickel complex with (S)-limonene based aminooxime ligand has been isolated and its crystal structure determined. The resolved structure of dichloridobis{(2S,5R)-2-methyl-5-(prop-1-en-2-yl)-2-[(pyridin-2-yl)methylamino]cyclohexan-1-one oxime}dinickel(II), [Ni2Cl2(C16H23ClN3O)2], at 100 K has monoclinic (P21) symmetry. The two NiII ions in the dinuclear complex are each coordinated in a distorted octahedral environment by three nitrogen atoms, a terminal chloride and two μ bridging chlorides. Each oxime ligand is coordinated to nickel(II) by the three nitrogen atoms, leading to two five-membered chelate rings, each displaying an envelope conformation. In the crystal, numerous intermolecular and intramolecular hydrogen bonds lead to the formation of a three-dimensional network structure.

Diterbium hepta-nickel: a crystal structure redetermination.

Project description:The crystal structure of the title compound, Tb2Ni7, was redetermined from single-crystal X-ray diffraction data. In comparison with previous studies based on powder X-ray diffraction data [Lemaire et al. (1967). C. R. Acad. Sci. Ser. B, 265, 1280-1282; Lemaire & Paccard (1969). Bull. Soc. Fr. Mineral. Cristallogr. 92, 9-16; Buschow & van der Goot (1970). J. Less-Common Met. 22, 419-428], the present redetermination affords refined coordinates and anisotropic displacement parameters for all atoms. A partial occupation for one Tb atom results in the non-stoichiometric composition Tb1.962?(4)Ni7. The title compound adopts the Ce2Ni7 structure type and can also be derived from the CaCu5 structure type as an inter-growth structure. The asymmetric unit contains two Tb sites (both site symmetries 3m.) and five Ni sites (.m., mm2, 3m., 3m., -3m.). The two different coordination polyhedra of Tb are a Frank-Kasper polyhedron formed by four Tb and 12 Ni atoms and a pseudo Frank-Kasper polyhedron formed by two Tb and 18 Ni atoms. The four different coordination polyhedra of Ni are Frank-Kasper icosa-hedra formed by five Tb and seven Ni atoms, four Tb and eight Ni atoms, three Tb and nine Ni atoms, and six Tb and six Ni atoms, respectively.

Crystal structure and magnetic properties of (tris-{4-[1-(2-meth-oxy-eth-yl)imidazol-2-yl]-3-aza-but-3-enyl}amine)-iron(II) bis-(hexa-fluorido-phosphate).

Project description:In the complex cation of the title compound, [Fe(C27H41N10O3)](PF6)2, the tripodal tris-{4-[1-(2-meth-oxy-eth-yl)imidazol-2-yl]-3-aza-but-3-en-yl}amine ligand is coordinated to an FeII ion through the nitro-gen atoms of three imidazole and three imino groups. The Fe atom exhibits a distorted octa-hedral geometry. In the crystal, l and d anti-podes are arranged in layers in the bc plane. Weak C?F and C-H?F/O contacts exist between the ligands of the complex cation and the PF6 - anions, generating a three-dimensional network. At 120?K, the FeII ion is in a low-spin state, with an average Fe-N bond distance of 1.970?(2)?Å. On heating, the FeII ion converts to the high-spin state, as demonstrated by magnetic susceptibility measurements.
