Crystal structure of bis-[?-2-(diiso-propyl-phosphor-yl)propan-2-olato-?(3) O (1),O (2):O (1)]bis-[chlorido-oxidovanadium(IV)].

ABSTRACT: The dinuclear mol-ecule of the title complex, [VOCl{?-OC(Me)2P(iPr)2-?(2) O}]2 or [V2(C9H20O2P)2Cl2O2], which was obtained due to an unexpected oxidation reaction, is centrosymmetric, with the inversion centre located in the middle of the central V2O2 core. These core O atoms arise from the symmetry-related 2-(diiso-propyl-phosphor-yl)propan-2-olate dianions. The V(IV) atom is additionally bonded to one terminal Cl ligand, the second O atom of the dianion and double bonded to a vanadyl O atom, leading to an overall distorted square-pyramidal VO4Cl coordination polyhedron with the vanadyl O atom as the apex. An intra-molecular C-H?Cl contact helps to establish the mol-ecular configuration. In the crystal, mol-ecules are stacked in rows parallel to [001] and are linked by C-H?Cl contacts to form chains running in the same direction.

[Bis(2,6-diiso-propyl-phen-yl) phosphato-κO]pentakis-(methanol-κO)manganese bis-(2,6-diiso-propyl-phen-yl) phosphate methanol tris-olvate.

Project description:The title compound, [Mn(C24H34O4P)(CH3OH)5](C24H34O4P)·3CH3OH, was formed in the reaction between a hydrate of a manganese(II) salt [either Mn(NO3)2(H2O)6 or MnCl2(H2O)4] with a methanol solvate of lithium bis-(2,6-diiso-propyl-phen-yl) phosphate, {Li[OOP(O-2,6- i Pr2C6H3)2]·(CH4O)3}·CH4O, in methanol. The structure has monoclinic (Cc) symmetry at 150 K. The complex consists of an [Mn{OOP(O-2,6- i Pr2C6H3)2}(CH3OH)5]+ cation, an [OOP(O-2,6- i Pr2C6H3)2]- anion and three non-coordinating methanol mol-ecules. The anion demonstrates disorder of an isopropyl group [occupancy ratio is 0.57 (4):0.43 (4)]. The di-aryl-phosphate ligand in the cation exhibits a κ1 O terminal coordination mode. The Mn atom is in a nearly unperturbed octa-hedral environment. The [Mn{OOP(O-2,6- i Pr2C6H3)2}(CH3OH)5]+ cation exhibits one intra-molecular O-H⋯O bond, and is coordinated via two inter-molecular O-H⋯O hydrogen bonds to the [OOP(O-2,6- i Pr2C6H3)2]- anion. The cations, anions and non-coordinating methanol mol-ecules are linked into infinite chains along the c-axis direction via 0-H⋯O hydrogen bonding. The complex is of inter-est as a possible inhibitor for the thermal decomposition of polydi-methyl-siloxane. The crystal studied was refined as an inversion twin with a domain ratio of 0.47 (3):0.53 (3).

Project description:The title compound, [Ag2(NO3)2(C14H38B10P2)2]·2CH2Cl2, was synthesized by the reaction of 1,2-bis-(diiso-propyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with AgNO3. The resulting dinuclear molecule has crystallographically imposed inversion symmetry. The diiso-propyl-phosphanyl-closo-carborane ligand is coordin-ated in a bidentate manner to the Ag(I) atom through the two P atoms. The distorted tetra-hedral coordination of the metal is completed by two O atoms of two bridging nitrate anions. The separation between the two Ag(I) atoms is 3.8913 (5) Å. C-H⋯O hydrogen bonds are observed involving the dichloromethane solvent molecule and the nitrate anion.

Di-?-chlorido-bis-[diacetonitrile-chlorido-oxidovanadium(IV)].

Project description:The title compound, [V(2)Cl(4)O(2)(CH(3)CN)(4)], is a centrosymmetric dinuclear V(IV) complex associated with four mol-ecules of acetonitrile. The coordination around both V(IV) atoms is essentially square-planar, involving three Cl atoms and one O atom [maximum deviation = 0.017?(3)?Å for the O atom]. The augmented octahedral coordination of the metal atom is completed by the N atoms of acetonitrile ligands. The V(IV) atoms are linked by two Cl atoms, acting as bridging atoms. The crystal studied was a non-merohedral twin with a ratio of the two twin components of 0.8200?(3):0.1800?(3). Although Cl and O atoms are present as potential acceptors in the title compound, no hydrogen bonds were observed in the crystal structure.

Crystal structure of di-μ-iodido-bis-{[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]lithium}.

Project description:In the title binuclear complex, [Li2(C27H36N2)2I2], the unique Li(I) cation is coordinated by two iodide anions and one yl-idene C atom from a 1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene ligand in a distorted trigonal-planar geometry. The two symmetry-related iodide anions bridge two Li(I) cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imidazol-2-yl-idene ring, with a dihedral angle of 85.5 (3)°. No hydrogen bonding is observed in the crystal.

Crystal structure of bis-(diiso-propyl-ammonium) molybdate.

Project description:The organic-inorganic title salt, (C6H16N)2[MoO4] or ( i Pr2NH2)2[MoO4], was obtained by reacting MoO3 with diiso-propyl-amine in a 1:2 molar ratio in water. The molybdate anion is located on a twofold rotation axis and exhibits a slightly distorted tetra-hedral configuration. In the crystal structure, the diiso-propyl-ammmonium ( i Pr2NH2)+ cations and [MoO4]2- anions are linked to each other through N-H⋯O hydrogen bonds, generating rings with R 12 12(36) motifs that give rise to the formation of a three-dimensional network. The structure was refined taking into account inversion twinning (ratio of ca 4:1 between the two domains).

Poly[μ-(1,3-dihy-droxy-propan-2-olato)-potassium].

Project description:The asymmetric unit of the title compound, [K(C(3)H(7)O(3))](n) or K[H(2)gl](n), common name potassium glycerolate, contains half the K(+) cation and half of the glycerolate anion. The other half of the anion is generated through a mirror plane passing through the K atom, and a C, an H and an O atom of the glycerolate ligand. The K(+) ion is coordinated by the O atoms of the OH groups, leading to a six-membered chelate ring that adopts a very distorted boat conformation. The negatively charged O atom of the glycerolate anion, [H(2)gl(-)], is found in the flagpole position and forms an ionic bond with the K(+) ion. The O atoms of the hydroxo groups are coordinated to two K(+) ions, whereas the negatively charged O atom is bonded to one K(+) ion. The K(+) ion is coordinated by three other symmetry-related monodentate H(2)gl(-) ligands, so that each H(2)gl(-) ligand is bonded to two K(+) ions, and the potassium has a seven-coordinate environment. The H(2)gl(-) ligands are connected via a strong O-H⋯O hydrogen bond and, together with the K⋯O inter-connections, form polymeric sheets which propagate in the directions of the a and b axes.

Crystal structure of di-μ-chlorido-bis-[di-chlorido(l-histidinium-κO)cadmium(II)].

Project description:In the title compound, [Cd2(C6H9N3O2)2Cl6], the coordination polyhedra around the CdII cations are distorted trigonal bipyramids. Two of the chloride ions (one axial and one equatorial) are bridging to the other metal atom, leading to a Cd⋯Cd separation of 3.9162 (4) Å. The O atom of the l-histidinium cation lies in an axial site. In the crystal, numerous N-H⋯Cl, N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional network. Theoretical calculations and spectroscopic data are available as supporting information.

catena-Poly[[(benzil bis{[(pyridin-2-yl)methylidene]hydrazone}-κ⁴N,N',N'',N''')mercury(II)]-μ-chlorido-[dichloridomercury(II)]-μ-chlorido].

Project description:In the title coordination polymer, [Hg₄Cl₄(C₂₆H₂₀N₆)](n), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl⁻ ions in a very distorted cis-HgCl₂N₄ octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl⁻ ions. Bridging chloride ions link the Hg(II) ions into a chain propagating in [010]: the Hg-Cl bridging bonds are significantly longer than the terminal bonds. The dihedral angle between the central benzene rings of the ligand is 83.3 (2)°. The packing is consolidated by weak C-H⋯Cl hydrogen bonds and C-H⋯π inter-actions.

Crystal structure of bis-[μ-bis-(di-phenyl-phosphan-yl)methane-κ(2) P:P']-μ-chlorido-chlorido-1κCl-(1-phenyl-thio-urea-2κS)disilver aceto-nitrile hemisolvate.

Project description:In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag⋯Ag separation of 3.2064 (2) Å. In the crystal, complex mol-ecules are linked by N-H⋯Cl hydrogen bonds forming a dimer. The dimers are linked via weak C- H⋯Cl hydrogen bonds forming a two-dimensional supra-molecular architecture in the yz plane. In addition, an intra-molecular N-H⋯Cl hydrogen bond is observed.

Di-μ-oxido-bis-({(R)-(-)-2-[1-(2-amino-propyl-imino)eth-yl]-1-naphtholato-κN,N',O}oxidovanadium(V)).

Project description:In the title dinuclear compound, [V(2)(C(15)H(17)N(2)O)(2)O(4)], each V(V) atom is six-coordinated by one oxide group, and by two N and one O atom of the tridentate Schiff base ligand, and bridged by two additional oxide O atoms, resulting in a centrosymmetric dimer. The metal centre has a distorted octa-hedral coordination with the monoanionic Schiff base ligand occupying one equatorial and two axial coordination positions. The separation between V atoms is 3.214 (3) Å. In the crystal structure, there are N-H⋯O, C-H⋯O and C-H⋯π hydrogen bonds, and π-π inter-actions.
