Hexa-?(2)-acetato-?O:O'-?(3)-oxido-tris-[aqua-chromium(III)] nitrate acetic acid solvate.

ABSTRACT: In the crystal structure of the title salt, [Cr(3)(C(2)H(3)O(2))(6)O(H(2)O)(3)]NO(3)·CH(3)CO(2)H, the trinuclear [Cr(3)(CH(3)CO(2))(6)O(H(2)O)(3)] cluster cation has an oxide O atom that is connected to three water-coordinated Cr(III) atoms, the three metal atoms forming the points of an equilateral triangle. Each of the six acetate carboxyl-ate groups bridges a Cr-O-Cr fragment. The cluster cation inter-acts with the nitrate counter-ion and solvent mol-ecules through O-H?O hydrogen bonds, forming a three-dimensional hydrogen-bonded network.

Hexa-μ(2)-acetato-triaqua-μ(3)-oxido-triiron(III) nitrate acetic acid solvate.

Project description:The asymmetric unit of the title compound, [Fe(3)(CH(3)COO)(6)O(H(2)O)(3)]NO(3)·CH(3)COOH, consists of a hexa-μ(2)-acetato-triaqua-μ(3)-oxo-triiron(III) macrocation, a nitrate ion and an acetic acid solvent mol-ecule. In the cation, each Fe(3+) ion is coordinated by four carboxyl-ate O atoms, one central bridged O atom and one water mol-ecule, resulting in distorted FeO(6) octa-hedra. A network of O-H⋯O hydrogen bonds helps to establish the packing.

Project description:In the title compound, [CuNa(3)(CH(3)CO(2))(5)(CH(3)COOH)(H(2)O)(2)](n), the Cu(II) atom lies on an inversion center and is coordinated by four O atoms from four acetate ligands, leading to a square-planar geometry. One Na(I) atom, lying on an inversion center, is coordinated by four O atoms from four acetate ligands and two bridging water mol-ecules in a distorted octa-hedral geometry. The other Na(I) atom is coordinated by five O atoms from five acetate ligands and a bridging water mol-ecule. A hy-droxy H atom lies on a twofold rotation axis and is shared by two acetate ligands. The crystal packing exhibits a polymeric layer parallel to (100), which is further stablized by intra-layer O-H⋯O hydrogen bonds. The layers are linked by inter-layer O-H⋯O hydrogen bonds.

Low-temperature redetermination of hexa-kis(μ-chloro-acetato-κO:O')-μ(3)-oxido-tris[aquachromium(III)] nitrate 3.5-hydrate.

Project description:A low-temperature redetermination of the trinuclear cluster compound described as [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3H(2)O [Glowiak, Kubiak & Jezowska-Trzebiatowska (1977 ▶). Bull. Acad. Pol. Sci. Ser. Sci. Chim.25, 359-371] shows that the salt is a 3.5-hydrate, [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3.5H(2)O. The trinuclear cluster cation is disordered in four of the six monochloro-acetate groups. One is disordered over two positions in respect of the chloro-methyl atoms (occupancy ratio 0.50:0.50); another is disordered over three positions in respect of the chloro-methyl atoms (occupancy ratio 0.50:0.37:0.13) whereas two are disordered over two positions in respect of the Cl atoms only (occupancy ratios 0.84:0.16 and 0.60:0.40). Of the four independent uncoordinated water mol-ecules, one has an occupancy factor of 0.5. The trinuclear cation has an oxido O atom that is connected to three water-coordinated Cr(III) atoms, the three metal atoms forming the points of an equilateral triangle. Six carboxyl-ate groups each chelate a Cr-O-Cr fragment. The cations, anions and uncoordinated water mol-ecules are linked by hydrogen bonds.

Hexa-μ(2)-acetato-κO:O'-(azido-κN)bis-(methanol-κO)-μ(3)-oxido-trichromium(III) methanol monosolvate.

Project description:In the crystal structure of the title complex, [Cr(3)(CH(3)CO(2))(6)(N(3))O(CH(3)OH)(2)]·CH(3)OH, the trinuclear core has a central O atom; two methanol mol-ecules and an azide ion are coordinated to the Cr(III) atoms in the core. The three Cr(III) atoms form vertices of a nearly equilateral triangle. Each of the six acetate carboxyl-ate groups bridges a Cr-O-Cr fragment. In the crystal, the molecules inter-act with methanol solvent mol-ecules through O-H⋯O and O-H⋯N hydrogen bonds, forming a two-dimensional hydrogen-bonded network parallel to (100).

Project description:In the title compound, [Co(C(10)H(8)N(2))(3)][Mo(6)O(19)], the Co(2+) cation is surrounded in a distorted octa-hedral coordination by six N atoms from three 2,2'-bipyridine ligands. The distribution of Mo-O bond lengths in the Lindqvist isopolyanion is consistent with other structures containing the same unit. In the crystal, the cations and anions are linked by C-H⋯O inter-actions.

Octa-methyldi-μ(3)-oxido-bis-(μ(2)-thio-phene-3-acetato-κO:O')(thio-phene-3-acetato-κO)tetra-tin(IV).

Project description:In the centrosymmetric title compound, [Sn(4)(CH(3))(8)(C(6)H(5)O(2)S)(4)O(2)], the central four-membered planar ring (Sn(2)O(2)) makes dihedral angles of 66.28 (12) and 77.43 (11)° with the heterocyclic rings of the bridging and monodentate ligands, respectively. One Sn(IV) atom adopts a distorted SnO(3)C(2) trigonal-bipyramidal geometry, with both C atoms in equatorial sites and the other a grossly distorted SnO(4)C(2) octa-hedral or irregular arrangement. In the crystal, the mol-ecules are connected into pillar-like polymeric units making R(2) (2)(12) ring motifs due to inter-molecular C-H⋯O inter-actions. C-H⋯π inter-actions are also present. The O atoms of the chelating ligands and the S atom of the monodentate ligand are disordered over two sets of sites in a 0.65 (6):0.35 (6) ratio.

Diaqua-?(3)-oxido-hexa-kis(?(2)-trichloro-acetato-?O:O')(trichloro-acetato-?O)trichromium(III) acetonitrile tris-olvate.

Project description:In the crystal structure of the title compound, [Cr(3)(C(2)Cl(3)O(2))(7)O(H(2)O)(2)]·3CH(3)CN, the trinuclear [Cr(3)O(H(2)O)(2)(Cl(3)CCO(2))(7)] mol-ecule has an oxide O atom that is connected to one monodentate trichloro-acetate-coordinated and two water-coordinated Cr(III) atoms, the three metal atoms forming the points of an equilateral triangle. Each of the six remaining carboxyl-ate groups bridges a Cr-O-Cr fragment. The cluster inter-acts with the three solvent mol-ecules through water-acetonitrile O-H?N hydrogen bonds. Adjacent clusters are linked by a water-carboxylate O-H?O hydrogen bond to give a helical chain. One of the CCl(3) groups was found to be disordered over two positions, with the major component having a site-occupancy factor of 0.64?(1).
