Hexaaqua-iron(II) bis-[fac-tribromido-tricarbonyl-ferrate(II)].

ABSTRACT: In the title compound, [Fe(H(2)O)(6)][FeBr(3)(CO)(3)](2), both Fe atoms have an octa-hedral coordination and the bromide carbonyl complex has a fac-stereochemistry. The [Fe(H(2)O)(6)](2+) octa-hedron has point symmetry and is slightly compressed along one O-Fe-O axis. The [FeBr(3)(CO)(3)](-) anion has point symmetry 1 and mean bond lengths of Fe-Br = 2.455?(5)?Å and Fe-C = 1.809?(2)?Å. The cation and anion complexes are mutually linked via O-H?Br hydrogen bonds with O?Br distances of 3.340?(3) to 3.388?(3)?Å.

fac-Bis(acetonitrile-?N)tricarbonyl-(trifluoro-acetato-?O)rhenium(I).

Project description:In the title compound, [Re(CF(3)COO)(CH(3)CN)(2)(CO)(3)], the Re atom has a distorted octa-hedral configuration. The two acetonitrile mol-ecules and two of the three carbonyl groups occupy the equatorial plane of the complex, with the third carbonyl ligand and the trifluoroacetato ligand in the axial positions. The three carbonyl ligands are arranged in a fac configuration around the Re atom. The CF(3) segment of the trifluoroacetato ligand shows rotational disorder and the refined site-occupancy factors of the disordered parts are ca 0.5/0.5. The crystal structure is stabilized by C-H?O and C-H?F hydrogen bonds.

Hexaaqua-magnesium(II) bis-(pyridinium-2,6-dicarboxyl-ate).

Project description:In the title compound, [Mg(H(2)O)(6)](C(7)H(4)NO(4))(2), a single six-coordinate Mg(2+) cation (site symmetry 2/m) is bonded to six water mol-ecules in a distorted octa-hedral geometry. The crystal packing between the complex cation and the zwitterionic organic cation (m symmetry) is stabilized by inter-molecular O-H?O hydrogen bonds and weak inter-molecular C-H?O inter-actions.

Hexaaqua-magnesium(II) bis-(d-camphor-10-sulfonate).

Project description:The structure of the title complex, [Mg(H(2)O)(6)](C(10)H(15)O(4)S)(2), consists of regular octa-hedral [Mg(H(2)O)(6)](2+) cations and d-camphor-10-sulfonate anions. A three-dimensional supra-molecular architecture is formed via hydrogen-bond inter-actions [O-H?O = 2.723?(2)-2.833?(2)?Å] to give alternating layers of [Mg(H(2)O)(6)](2+) cations and d-camphor-10-sulfonate anions. The title compound is isomorphous with the zinc, copper, cadmium and nickel analogues.

Hexaaqua-zinc(II) bis-(4-hydroxy-benzene-sulfonate) dihydrate.

Project description:In the crystal structure of the title compound, [Zn(H(2)O)(6)](C(6)H(5)O(4)S)(2)·2H(2)O, the Zn(II) atom lies on a center of inversion. The complex cation inter-acts with the anion and uncoord-inated water mol-ecules by O-H?O hydrogen bonds, generating a three-dimensional network. The anion is disordered over two equal positions along the hydr-oxy-sulfonate C-C axis.

Hexaaqua-cobalt(II) bis-(4-amino-3-methyl-benzene-sulfonate).

Project description:In the title mol-ecular salt, [Co(H(2)O)(6)](C(7)H(8)NO(3)S)(2), the Co(2+) cation lies on an inversion centre. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds, thereby generating sheets parallel to (001).

Hexaaqua-zinc(II) dichloride bis-(hexa-methyl-enetetramine) tetra-hydrate.

Project description:The title compound, [Zn(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, has been prepared under mild hydro-thermal conditions. The Zn(II) atom, located on a centre of symmetry, is coordinated by six water mol-ecules in a distorted octa-hedral coordination geometry. The hexa-methyl-enetetra-mine mol-ecule is not coordinated to Zn(II) but links the Zn complexes via three O-H?N hydrogen bonds. The remaining N atom of the hexa-methyl-enetetra-mine mol-ecule is hydrogen-bonded to a solvent water mol-ecule. In the crystal structure, inter-molecular O-H?O, O-H?N and O-H?Cl hydrogen bonds link the components into a three-dimensional network.

Tricarbonyl-bis-(1,3-diisopropyl-4,5-dimethyl-imidazol-2-yl-idene)iron.

Project description:In the title compound, [Fe(C11H20N2)2(CO)3], the Fe atom shows a distorted trigonal-bipyramidal geometry with three carbonyl and two carbene ligands. The latter have a cis arrangement, with a C-Fe-C angle of 90.60?(7)°. The Fe atom lies 0.007?(1)?Å above the basal plane defined by two carbonyl and one carbene C atoms. The mol-ecular structure is closely related to that of the isomolecular but not isotypic Ru complex with an identical cis arrangement, so, in general, bond geometries lie in expected ranges. In the crystal, C-H?O hydrogen bonds link the mol-ecules into infinite zigzag chains extending along [010].

Hexaaqua-cobalt(II) bis-(2,2'-sulfanediyldiacetato-κO,S,O')cobaltate(II) tetra-hydrate.

Project description:The two Co(II) atoms in the title salt, [Co(H(2)O)(6)][Co(C(4)H(4)O(4)S)(2)]·4H(2)O, exist in an octa-hedral coordination environment. In the cation, the Co atom is surrounded by six water mol-ecules, and in the anion, it is bis-O,S,O'-chelated by the thio-acetate ligands. The cations, anions and uncoordinated water mol-ecules are linked by O-H⋯O hydrogen bonds into a three-dimensional network.

μ(4)-Sulfido-bis-{(μ-2-furyl-methane-thiol-ato)bis-[tricarbonyl-iron](Fe-Fe)}.

Project description:The title compound, [Fe(4)(C(5)H(5)OS)(2)S(CO)(12)], was prepared by the direct reaction of Fe(3)(CO)(12) and 2-furyl-methane-thiol in tetra-hydro-furan. Desulfurization took place readily to form an Fe(4)S(3) cluster. The mol-ecule consists of two similar [(μ-2-C(4)H(3)O-CH(2)S)Fe(2)(CO)(6)] moieties joined to a spiro-type four-coordinate μ(4)-S atom such that this bridging sulfur is tetra-hedrally coordinated to the four Fe atoms. In each diiron subcluster core, the 2-furyl-methane-thiol-ate ligand bridges the two Fe atoms.

Project description:In the title compound, [Co(H(2)O)(6)](C(9)H(7)O(4))(2)·2H(2)O, the Co(2+) cation lies on a twofold rotation axis and is coordinated by six water mol-ecules in a distorted octa-hedral geometry. In the 5-acetyl-2-hy-droxy-benzoate anion, the hy-droxy group links with the carboxyl-ate group via an intra-molecular O-H?O hydrogen bond and the acetyl group is twisted to the benzene ring at a dihedral angle of 16.99?(12)°. In the crystal structure, the cations, anions and water mol-ecules are linked by extensive O-H?O hydrogen bonding.
