(Methanol-?O)-cis-dioxido{(4Z,N'E)-N'-[(Z)-4-oxido-4-phenyl-but-3-en-2-yl-idene]iso-nicotino-hydrazidato}molybdenum(VI).

ABSTRACT: In the title complex, [Mo(C16H13N3O2)O2(CH3OH)], the deprotonated Schiff base (E)-N'-[(Z)-4-oxido-4-phenyl-but-3-en-2-yl-idene]isonicotinohydrazide coordinates in a meridional fashion through the enolate O-, imine N- and amidate O-atom donors to the Mo atom of a cis-[MoO2](2+) core. The sixth coordination site of molybdenum is occupied by the O atom of a methanol mol-ecule. In this complex, the NO5 coordination sphere adopts a distorted octa-hedral coordination geometry. The metal atom is shifted by 0.335?(1)?Å from the square plane defined by the three donor atoms of the Schiff base ligand and one oxide group towards the second oxide group in the cis position. In the crystal, the complex forms inversion dimers through a pair of O-H?N hydrogen bonds involving the methanol -OH group and the pyridine N atom. Additional C-H?O contacts stack the mol-ecules along the b axis.

Tetra-?-oxido-tetra-kis{dioxido[3-(2-pyrid-yl)-1H-pyrazole]molybdenum(VI)}.

Project description: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).

?-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.

A new Mo Schiff base complex: methanol[N'-(3-meth-oxy-2-oxidobenzyl-idene)benzohydrazidato]dioxido-molybdenum(VI).

Project description:In the title benzil-idene Schiff base molybdenum(VI) complex, [Mo(C(15)H(12)N(2)O(3))O(2)(CH(3)OH)], the Mo(VI) ion is coordinated by two oxide O atoms and by two O atoms and one N atom of the tridentate N'-(3-meth-oxy-2-oxidobenzyl-idene)benzo-hydrazidate (L) Schiff base ligand. The methanol O atom completes the distorted octa-hedral configuration of the Mo(VI) atom. Strong O-H⋯N hydrogen bonds form a C(5) chain around a 2(1) screw axis. Weak C-H-O hydrogen bonds are also present.

A binuclear molybdenum oxyfluoride: ?-oxido-bis-[(2,2'-bipyrid-yl)fluoridodioxidomolybdenum(VI)].

Project description:The title compound, [Mo(2)F(2)O(5)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear molybdenum(VI) species with the metal atoms in a distorted octa-hedral environment. The coordination geometries of the symmetry-equivalent molybdenum sites are defined by the cis-terminal oxide groups and the N-atom donors of the bipyridyl ligand in the equatorial plane with axial F and bridging O atoms. The bridging O atom occupies a center of symmetry. The mol-ecules stack in the a-axis direction, and the crystal packing is stabilized by weak intra- and inter-molecular C-H?O and C-H?F hydrogen bonds.

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.

A Model for the Active-Site Formation Process in DMSO Reductase Family Molybdenum Enzymes Involving Oxido-Alcoholato and Oxido-Thiolato Molybdenum(VI) Core Structures.

Project description:New bis(ene-1,2-dithiolato)-oxido-alcoholato molybdenum(VI) and -oxido-thiolato molybdenum(VI) anionic complexes, denoted as [Mo(VI)O(ER)L2](-) (E = O, S; L = dimethoxycarboxylate-1,2-ethylenedithiolate), were obtained from the reaction of the corresponding dioxido-molybdenum(VI) precursor complex with either an alcohol or a thiol in the presence of an organic acid (e.g., 10-camphorsulfonic acid) at low temperature. The [Mo(VI)O(ER)L2](-) complexes were isolated and characterized, and the structure of [Mo(VI)O(OEt)L2](-) was determined by X-ray crystallography. The Mo(VI) center in [Mo(VI)O(OEt)L2](-) exhibits a distorted octahedral geometry with the two ene-1,2-dithiolate ligands being symmetry inequivalent. The computed structure of [Mo(VI)O(SR)L2](-) is essentially identical to that of [Mo(VI)O(OR)L2](-). The electronic structures of the resulting molybdenum(VI) complexes were evaluated using electronic absorption spectroscopy and bonding calculations. The nature of the distorted O(h) geometry in these [Mo(VI)O(EEt)L2](-) complexes results in a lowest unoccupied molecular orbital wave function that possesses strong π* interactions between the Mo(d(xy)) orbital and the cis S(p(z)) orbital localized on one sulfur donor from a single ene-1,2-dithiolate ligand. The presence of a covalent Mo-S(dithiolene) bonding interaction in these monooxido Mo(VI) compounds contributes to their low-energy ligand-to-metal charge transfer transitions. A second important d-p π bonding interaction derives from the ∼180° O(oxo)-Mo-E-C dihedral angle involving the alcoholate and thiolate donors, and this contributes to ancillary ligand contributions to the electronic structure of these species. The formation of [Mo(VI)O(OEt)L2](-) and [Mo(VI)O(SEt)L2](-) from the dioxidomolybdenum(VI) precursor may be regarded as a model for the active-site formation process that occurs in the dimethyl sulfoxide reductase family of pyranopterin molybdenum enzymes.

N'-(But-2-enyl-idene)-iso-nicotino-hydrazide.

Project description:In the title Schiff base compound, C(10)H(11)N(3)O, the pyridine ring is twisted with respect to the mean plane containing the hydrazine chain, making a dihedral angle of 31.40 (9)°. The NH group inter-acts with the N atom of the pyridine ring through N-H⋯N hydrogen bonds to build up a zigzag chain developing parallel to the (01) plane.

Tetra-μ(2)-acetato-tetraaquadi-μ(3)-oxido-octaoxidotetrauranium(VI) methanol disolvate tetrahydrate.

Project description:The centrosymmetric title tetra-mer, [U(4)(C(2)H(3)O(2))(4)O(10)(H(2)O)(4)]·2CH(4)O, has a near planar core [maximum deviation from the least squares plane of 0.294 (6) Å]. It consists of two hexa-gonal-bipyramidally coordinated U(VI) atoms connected via μ(2)-O (acetate) and μ(3)-O (oxide) bridges in the equatorial plane to two penta-gonal-bipyramidally coordinated U(VI) atoms. The equatorial plane of each U(VI) atom is completed by a bound water mol-ecule, while the axial positions are occupied by uranyl (UO(2))(2+) O atoms. Multiple O-H⋯O hydrogen bonds are present, including a lattice methanol mol-ecule bound to one of the penta-gonal bipyramidal uranyl O atoms, as well as two different C(1) (1)(6) chains orginating from a donor water mol-ecule, via a uranyl oxygen acceptor and an acetate acceptor on different, adjacent tetra-mers. Finally, the unit cell contains four U(VI) tetra-mers, all connected by hydrogen bonding, forming a supra-molecular R(4) (4)(24) ring.
