ABSTRACT: In the title compound, [Mo(4)O(12)(C(8)H(7)N(3))(4)], the Mo(VI) ion has a distorted octa-hedral coordination completed by two terminal O atoms, two ?-oxide atoms and two N atoms from one 3-(2-pyrid-yl)-1H-pyrazole ligand. It is noteworthy that in the tetranuclear unit ( symmetry), any three Mo(VI) atoms define a plane, and the fourth lies 1.8?(1)?Å out of that plane. The degree of linearity of the oxide bridges between two Mo atoms is 175.38?(13)°. Moreover, the N-H group forms an intra-molecular hydrogen bond (four per mol-ecule).

Project description:The asymmetric unit of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[SiMo(14)O(44)], consists of a complex [Fe(C(8)H(7)N(3))(3)](2+) cation and half of a derivative of an α-Keggin-type anion, [SiMo(14)O(44)](4-). In the mixed-valent Mo(V/VI) anion, the α-Keggin type core is capped on two oppositely disposed tetra-gonal faces by additional (MoO(2)) units. The [SiMo(14)O(44)](4-) anion shows disorder. Two O atoms of the central SiO(4) group ( symmetry) are equally disordered about an inversion centre. Moreover, two of the outer bridging O atoms and the O atoms of the capping (MoO(2)) unit are likewise disordered. The Fe(2+) cation is surrounded in a slightly distorted octa-hedral coordination by six N atoms from three 3-(2-pyrid-yl)-1H-pyrazole ligands. N-H⋯O hydrogen bonding between the cations and anions leads to a consolidation of the structure.

Tetra-kis(2-amino-4-methyl-pyridinium) cyclo-tetra-?(2)-oxido-tetra-kis-[dioxido-vanadate(V)] tetra-hydrate.

Project description:The asymmetric unit of the title compound, (C(6)H(9)N(2))(4)[V(4)O(12)]·4H(2)O, contains half of a [V(4)O(12)](4-) anion, two 2-amino-4-methyl-pyridinium, (2a4mpH)(+), cations and two water mol-ecules. One water mol-ecule is disordered over two sets of sites with equal occupancies and the H atoms for this mol-ecule were not included in the refinement. The cation lies on an inversion center with four tetra-hedral VO(4) units each sharing two vertices, forming an eight-membered ring. In the crystal, the components are linked by inter-molecular N-H?O hydrogen bonds, forming a one-dimensional network along [100]. Further stabilization is provided by weak inter-molecular C-H?O hydrogen bonds. In addition, ?-? stacking inter-actions with centroid-centroid distances of 3.5420?(18), 3.7577?(18) and 3.6311?(19)?Å are observed.

Poly[[2-(3-pyridinio)-1H,3H-benzimidazolium] [?(4)-oxido-di-?(3)-oxido-tetra-?(2)-oxido-hexa-oxidotetra-molybdenum(VI)]].

Project description:The reaction of MoO(3) with 2-(3-pyrid-yl)benzoimidazole and water in the presence of MnSO(4)·5H(2)O at 453?K under hydro-thermal conditions afforded the title compound, {(C(12)H(11)N(2))[Mo(4)O(13)]}(n), in which infinite molybdenum oxide anionic chains are charge-balanced by diprotonated 2-(3-pyrid-yl)benzoimidazole (H(2)3-PBIM(2+)) cations. Eight [MoO(6)] octa-hedra are edge-shared, forming compact octa-molybdate subunits which are connected through pairs of Mo-O-Mo bridges into extended one-dimensional arrays propagating along the a-axis direction. The asymmetric unit of the metal oxide chain contains one half of the octa-molybdate unit, denoted [Mo(4)O(13)], the other half being generated by an inversion center. These molybdenum oxide chains are further connected through the 2-(3-pyridinio)benzoimidazolium cations into a three-dimensional network via N-H?O hydrogen bonds. In addition, neighbouring diprotonated cations are arranged in a head-to-tail fashion with a plane-to-plane separation of 3.63?(10)?Å, indicating the existence of weak aromatic ?-? stacking inter-actions.

Tris{aqua-bis[3-(2-pyrid-yl)-1H-pyrazole]copper(II)} di-?(9)-arsenato-hexa-triaconta-?(2)-oxido-octa-deca-oxidoocta-deca-molybdate(VI).

Project description:The title compound, [Cu(C(8)H(7)N(3))(2)(H(2)O)](3)[As(2)Mo(18)O(62)], consists of two subunits, viz. an ?-Dawson-type [As(2)Mo(18)O(62)](6-) anion and a complex [Cu(C(8)H(7)N(3))(2)(H(2)O)](2+) cation. The copper(II) ion (site symmetry .2) is penta-coordinated in a distorted square-pyramidal manner by four N atoms from two chelating 3-(2-pyrid-yl)pyrazole ligands in equatorial positions and one water mol-ecule in the apical position. In the heteropolyanion, two O atoms of the AsO(4) group (3. symmetry) are equally disordered about the threefold rotation axis. N-H?O and O-H?O hydrogen bonding between the neutral mol-ecules and the water mol-ecules leads to a consolidation of the structure.

Poly[(μ-β-hexa-cosa-oxidoocta-molybdato)tetra-kis-[3-(2-pyrid-yl)pyrazole]-dizinc(II)].

Project description:In the hydro-thermally prepared title compound, [Mo(8)Zn(2)O(26)(C(8)H(7)N(3))(4)](n) or {[Zn(C(8)H(7)N(3))(2)](2)(Mo(8)O(26))}(n), the Zn(II) atom is coordinated by two N,N'-bidentate 3-(2-pyrid-yl)pyrazole ligands and two O atoms from adjacent octa-molybdate polyanions, generating a distorted cis-ZnO(2)N(4) octa-hedral geometry for the divalent metal ion. The complete octa-molbydate unit is generated by crystallographic inversion symmetry. The polyhedral connectivity leads to [100] chains in the crystal and N-H⋯O and N-H⋯(O,O) hydrogen bonds help to consolidate the packing.

Hexa-μ(2)-chlorido-μ(4)-oxido-tetra-kis-[(3-methyl-5-phenyl-1H-pyrazole-κN)copper(II)].

Project description:The title compound, [Cu(4)Cl(6)O(C(10)H(10)N(2))(4)], contains four Cu(II) atoms which are bridged by six chloride anions. The central O atom is located on a crystallographic fourfold roto-inversion axis. Each Cu(II) atom is coordinated by an N atom of a neutral monodentate 3-methyl-5-phenyl-pyrazole ligand, three Cl(-) anions, and one O(2-) anion. The geometry at each Cu(II) atom is distorted trigonal-bipyramidal, with the three Cl(-) ions in the equatorial plane and the N and O atoms in the axial positions.

Hexa-?-chlorido-?(4)-oxido-tetra-kis-({1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-?N}copper(II)).

Project description:The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and through three separate chloride-ion bridges. The fifth coord-ination position, located on the central Cu-O axis on the outside of the cluster, is occupied by an N atom of the mono-dentate 1-(pyridin-2-ylmeth-yl)-1H-benzimidazole ligand. The resulting coordination geometry of the metal ion is a distorted trigonal bipyramid with the O and N atoms in the axial positions. The dihedral angle between the benzimidazole ring system and the pendant pyridine ring is 61.0?(2)°.

Tetra-kis(diethyl ether)tetra-?(4)-oxido-octa-kis-(penta-fluoro-phen-yl)octa-zinc.

Project description:Mol-ecules of the title compound, [Zn(8)(C(6)F(5))(8)O(4)(C(4)H(10)O)(4)], are located on a special position of site symmetry [Formula: see text]. As a result, there is just one quarter-mol-ecule in the asymmetric unit. The title compound features a Zn(4)O(4) cube. Each Zn atom in the cube carries a pentafluorophenyl substituent. Each O atom is bonded to a further Zn atom, which is connected to a pentafluorophenyl substituent and the O atom of a diethyl ether mol-ecule. All ether C atoms are disordered over two sets of sites with a site occupation factor of 0.51?(2) for the major occupied site.

Bis[tris-(ethyl-enediamine-?N,N')cobalt(III)] octa-kis-?-(3)-oxido-hexa-deca-?(2)-oxido-tetra-deca-oxido-?(12)-tetra-oxo-silicato-octa-molybdenum(VI)hexa-vanadium(IV,V) hexa-hydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](2)[SiMo(8)V(4)O(40)(VO)(2)]·6H(2)O, was prepared under hydro-thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)(3)](3+) cation (en is ethyl-enediamine), one half of an [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion, two solvent water mol-ecules in general positions and two half-mol-ecules of water located on a mirror plane. In the complex cation, the Co(3+) ion is in a distorted octa-hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion is a four-electron reduced bivanadyl-capped ?-Keggin-type molybdenum-vanadium-oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra-hedral SiO(4) group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight ?(2)-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter-molecular N-H?O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra-molecular network.

?-Oxido-bis-[chlorido(4,4'-di-tert-butyl-2,2'-bipyridine-?N,N')dioxido-molybdenum(VI)] 0.2-hydrate.

Project description:The title hydrate, [Mo(2)Cl(2)O(5)(C(18)H(24)N(2))(2)]·0.2H(2)O, has been isolated as the oxidation product of [Mo(?(3)-C(3)H(5))Cl(CO)(2)(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A ?-oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O(2) units, having the terminal oxide ligands mutually cis, and the chloride and ?-oxide trans to each other. In the binuclear complex, the coordination geometries of the metal atoms can be described as highly distorted octa-hedra. Individual complexes co-crystallize with a partially occupied water mol-ecule of crystallization (occupancy factor = 0.20; H atoms not located), with the crystal packing being mediated by the need to effectively fill the available space. A number of weak C-H?O and C-H?Cl inter-actions are present.
