Redetermination of di-aqua-tris-(4-oxo-pent-2-en-2-olato-?(2) O,O')lanthanum(III).

ABSTRACT: The structure of the title compound, [La(C5H7O2)3(H2O)2], has been redetermined to modern standards with anisotropic displacement parameters for all non-H atoms and the hydrogen-bonding pattern unambiguously established [for the previous study, see Phillips et al. (1968 ?). Inorg. Chem. 7, 2295-2299]. The La(3+) ion is coordinated by three O,O'-bidentate acetyl-acetate (acac(-)) ligands and two water mol-ecules, resulting in a fairly regular square-anti-prismatic LaO8 coordination geometry, with both aqua ligands part of the same square face. In the crystal, the neutral complex mol-ecules are linked into [110] chains by O-H?O hydrogen bonds.

Structure of tri-aqua-tris-(1,1,1-tri-fluoro-4-oxo-pentan-2-olato)cerium(III) as a possible fluorescent compound.

Project description:Luminescence due to the d-f transition of Ce3+ is quite rare in metal-organic complexes where concentrate quenching frequently occurs. One of the possible ways to avoid this is to design an architecture with elongated metal-metal distances. In the structure of the title complex, tri-aqua-tris-(1,1,1-tri-fluoro-4-oxo-pentan-2-olato-?2O,O')cerium(III), [Ce(C5H4F3O2)3(H2O)3], the CeIII complex is linked to neighbouring ones by hydrogen bonding. Within the complex, the CeIII atom is coordinated by nine O atoms from three 1,1,1-tri-fluoro-4-oxo-pentan-2-olate (tfa) anions as bidentate ligands and three water mol-ecules as monodentate ligands. Thus, the coordination number of CeIII atom is nine in a monocapped square-anti-prismatic polyhedron. The F atoms of all three independent CF3 groups in tfa are disordered over two positions with occupancy ratios of about 0.8:0.2. The inter-molecular hydrogen bonds between the ligands involve tfa-water inter-actions along the [110] and [1-10] directions, generating an overall two-dimensional layered network structure. The presence of the F atoms in the tfa anion is responsible for an increased inter-molecular metal-metal distance compared to that in the analogous acetyl-acetonate (acac) derivatives. Fluorescence from Ce3+ is, however, not observed.

Diaqua-tris-[4,4,4-trifluoro-3-oxo-1-(thio-phen-2-yl)but-1-en-1-olato]neodymium(III) acetonitrile monosolvate.

Project description:The title complex, [Nd(C(8)H(4)F(3)O(2)S)(3)(H(2)O)(2)]·CH(3)CN, consists of an Nd(III) ion surrounded by three 4,4,4-trifluoro-3-oxo-1-(thio-phen-2-yl)but-1-en-1-olate ligands, coordinated through the O atoms, and two water mol-ecules. The Nd-O bond lengths range from 2.372?(2) to 2.513?(2)?Å. The metal ion displays a coordination number of eight and a square-anti-prismatic coordination geometry. A single uncoordinated acetonitrile mol-ecule is present in the asymmetric unit. Two of the three thio-phene rings are disordered, resulting from a 180° rotation with respect to the ?-diketonate moiety. The coordinated water mol-ecules act as hydrogen-bond donors towards the acetonitrile N atom and the ?-diketonate O atoms.

catena-Poly[[[tetra-aqua-lanthanum(III)]-di-?-isonicotinato-?(4)O:O'] chloride].

Project description:In the title compound, {[La(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the La(III) atom lies on a twofold rotation axis and is eight-coordinated by four O atoms from four isonicotinate ligands and four water mol-ecules in a distorted square-anti-prismatic coodination environment. Adjacent La(III) atoms are bridged by two carboxyl-ate groups from two isonicotinate ligands, forming an extended chain along [001]. These chains are linked through O-H?N hydrogen bonds into a three-dimensional network with channels in which the chloride anions form O-H?Cl hydrogen bonds. Intra-chain O-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.908?(2)?Å] are also observed.

Bis(?-2-methyl-quinolin-1-ium-8-olato-?O:O')bis-[(2-methyl-quinolin-1-ium-8-olato-?O)tris-(nitrato-?O,O')lanthanum(III)].

Project description:The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinuclear structure is further stabilized by intra-molecular N-H?O(nitrate) hydrogen bonds.

Poly[[tetra-aqua-tris-(?(3)-hexane-1,6-di-carboxyl-ato)diterbium(III)] 0.25-hydrate].

Project description:In the title terbium coordination polymer, {[Tb(2)(C(6)H(8)O(4))(3)(H(2)O)(4)]·0.25H(2)O}(n), the Tb(III) atom is nine-coordinated, forming a TbO(9) polyhedra. Furthermore, two symmetric TbO(9) polyhedra share their edges, forming Tb(2)O(16) dimers, which are linked by adipate bridges into a layered structure. Inter-molecular O-H?O hydrogen bonds link these layers into a three-dimensional network. One of the C atoms of the adipate ligand is disordered over two positions with site-occupancy factors of 0.622?(9) and 0.378?(9). The structure also contains a disordered mol-ecule of water of hydration, lying close to a special position, with partial occupancy.

[4,4'-(Ethane-1,2-diyldinitrilo)-bis-(pent-2-en-2-olato)]copper(II) 0.25-hydrate.

Project description:In the title compound, [Cu(C(12)H(18)N(2)O(2))]·0.25H(2)O, the coordination of the O,N,N',O'-tetra-dentate ligand results in a cis-CuN(2)O(2) square-planar geometry for the metal ion and the presence of two six-membered and one five-membered chelate rings. The complete complex mol-ecule is close to planar (r.m.s. deviation = 0.047?Å). The uncoordinated water mol-ecule (O-atom site symmetry 2) was modelled as half occupied. In the crystal, C-H?O(w) and O(w)-H?O (w = water) hydrogen bonds link the components into layers parallel to ab plane.

Crystal structure of di-aqua-tris-(benzohydrazide-?2 N,O)(isophthalato-?O)samarium(III) nitrate.

Project description:The first benzohydrazide complex of a lanthanide is reported. In the title compound, [Sm(C8H4O4)(C7H8N2O)3(H2O)2]NO3, systematic name di-aqua-tris-(benzohydrazide-?2 N,O)(isophthalato-?O)samarium(III) nitrate, the SmIII ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by three oxygen atoms and three nitro-gen atoms from three benzhydrazide (bzz) ligands, one oxygen atom from the isophthalate (itp2-) ligand, and two oxygen atoms from coordinated water mol-ecules. The nitrate group is disordered over two sets of sites with occupancy factors of 0.310?(17) and 0.690?(17). In the crystal, adjacent mol-ecules are linked into chains via pairs of O-H?O and N-H?O hydrogen bonds between the carboxyl-ate acceptor and the coordinated water and amine NH2 donors. Mol-ecules are further stacked by ?-? inter-actions involving the benzene ring of the itp2- ligands, forming double chains that extend in the b-axis direction. These double chains are further linked into a three-dimensional supra-molecular network via hydrogen bonds (O-H?O, N-H?O and C-H?O) between the complex mol-ecule and the nitrate groups along with C-H?? and ?-? inter-actions involving the benzene rings of the bzz and itp2- ligands.

Tris(ethanol-κO)tris-(picrato-κO,O)lanthanum(III) tri-2-pyridylamine solvate.

Project description:The title compound, [La(C(6)H(2)N(3)O(7))(3)(C(2)H(6)O)(3)]·C(15)H(12)N(4), has two mol-ecular building blocks, namely the neutral mononuclear adduct of lanthanum picrate with ethanol [i.e. La(pic)(3):EtOH (1:3); La(pic)(3) = lanthanum picrate and EtOH = ethanol] and the oligodentate aromatic nitro-gen base tri-2-pyridylamine (tpa). The asymmetric unit contains two formula units. The compound was prepared during an investigation of the stereochemistry of lanthanoid picrate complexes with O-donor ligands. The metal-ligand adduct adopts a nine-coordinate tricapped trigonal-prismatic metal atom environment. The stereochemical arrangement of the ligands about the metal core is typical of a fac-isomer with stoichiometry M(bidentate)(3)(monodentate)(3). Face-to-face hydrogen bonds are found between the tpa mol-ecule and the ethanol ligands. One ethanol ligand is disordered over two positions, with site occupancy factors of ca 0.7 and 0.3. The oxygen atoms of a nitro group are also disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.
