Bis(?-ferrocene-carboxyl-ato)bis-[aqua--bis(ferrocene-carboxyl-ato)methano-l-erbium(III)] methanol disolvate.

ABSTRACT: In the centrosymmetric title coordination compound, [Er(2){Fe(C(5)H(5))(C(6)H(4)O(2))}(6)(CH(3)OH)(2)(H(2)O)(2)]·2CH(3)OH, the two Er(III) ions are bridged by two ferrocene-carboxyl-ate anions as asymmetrically bridging ligands, leading to dimeric cores. The Er(III) ion has a distorted dodeca-hedral coordination with six coordinating O atoms derived from the ferrocene-carboxyl-ate ligands and two coordinated O atoms from one water mol-ecule and one methanol mol-ecule. The asymmetric unit comprises a half of the complex mol-ecule and a methanol solvent mol-ecule. Intra-molecular O-H?O and C-H?O inter-actions occur. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds and C-H?O as well as C-H?? inter-actions.

Tetra-kis(?(2)-ferrocene-carboxyl-ato-?O:O')bis-[(methanol-?O)copper(II)] methanol disolvate.

Project description:The complex mol-ecule of the title compound, [Cu(2)Fe(4)(C(5)H(5))(4)(C(6)H(4)O(2))(4)(CH(3)OH)(2)]·2CH(3)OH, lies about an inversion centre and contains two centrosymetrically related Cu(II) atoms bridged by four O:O'-bidentante ferrocene-carboxyl-ate anions, leading to a dimeric tetra-bridged unit with a paddle-wheel geometry. The Cu(II) atom has a distorted square-pyramidal coordination environment with four O atoms from four ferrocene-carboxyl-ate ligands in basal positions and an O atom from a methanol mol-ecule in an apical position. One of the two crystallographically independent ferrocenyl groups has a staggered conformation, while the other is eclipsed. The mol-ecules are connected into a chain along the b axis by O-H?O hydrogen bonds involving coordinated and uncoordinated methanol mol-ecules and the O atom from a ferrocene-carboxyl-ate unit.

Bis(ferrocene-carboxyl-ato-?O)bis-(2-pyridyl-methanol-?N,O)cobalt(II).

Project description:The title complex mol-ecule, [Fe(2)Co(C(5)H(5))(2)(C(6)H(4)O(2))(2)(C(6)H(7)NO)(2)], has a crystallographic imposed centre of symmetry. The Co(II) atom displays a distorted octa-hedral coordination geometry, provided by the O atoms of two monodentate ferrocene-carboxyl-ate anions and by the N and O atoms of two 2-pyridyl-methanol mol-ecule. The mol-ecular conformation is stabilized by intra-molecular C-H?O hydrogen bonds.

Bis(?-adamantane-1,3-dicarboxyl-ato-?O,O:O,O)bis-[aqua-(3-carboxy-adam-antane-1-carboxyl-ato-?O)(1,10-phen-an-throline-?N,N')erbium(III)] dihydrate.

Project description:The asymmetric unit of the binuclear centrosymmetric title compound, [Er(2)(C(12)H(14)O(4))(2)(C(12)H(15)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, contains one Er(III) atom, one coordinated water mol-ecule, one 1,10-phenanthroline (phen) ligand, two differently coordinated adamantane-1,3-dicarboxyl-ate (H(2)L) ligands and one lattice water mol-ecule. The Er(III) ion is eight-coordinated by four O atoms from bridging L(2-), one O atom from HL(-), one O atom from the coordinated water and two N atoms from a phen ligand. Extensive O-H?O hydrogen-bonding inter-actions result in the formation of chains which are further linked into a layer-like network by ?-? stacking inter-actions centroid-centroid distance = 3.611?(3)?Å] between adjacent phen ligands belonging to neighbouring chains. The carboxy group of the HL(-) ligand is equally disordered over two positions.

Bis-(?-pyridine-2,3-dicarboxyl-ato)bis-[aqua-(3-carb-oxy-pyridine-2-carboxyl-ato)indium(III)] tetra-hydrate.

Project description:In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]·4H(2)O, which contains both pyridine-2,3-dicarboxyl-ate and 3-carb-oxy-pyridine-2-carboxyl-ate ligands, the In(III) atom is six-coordinated in a distorted octa-hedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H?O hydrogen-bonding network, involving the coordinated and lattice water mol-ecules and the carboxyl groups of the ligands, together with C-H?O and ?-? inter-actions [centroid-centroid distance = 3.793?(1)?Å], leads to the formation of a three-dimensional structure.

Bis(triethyl-ammonium) bis-(μ-pyrazine-2,3-dithiol-ato)bis-(pyrazine-2,3-dithio-lato)diferrate(III) methanol disolvate.

Project description:In the title compound, (C(6)H(16)N)(2)[Fe(2)(C(4)H(2)N(2)S(2))(4)]·2CH(4)O, the [Fe(III)(pdt)(2)](-) anion (pdt is pyrazine-2,3-dithiol-ate) forms a centrosymmetric dimer supported by two Fe(III)-S bonds [Fe-S = 2.4787 (4) Å]. In the crystal structure, dimers form a one-dimensional stack along the b axis via π-π stacking inter-actions, the inter-planar separation between adjacent dimers being 3.51 (2) Å. The methanol solvent mol-ecule is involved in two hydrogen bonds in which the hydroxyl group acts as a hydrogen-bond donor to the N atom of a pdt ligand and the O atom acts as an acceptor for the NH group of the triethyl-ammonium cation.

Bis(?(3)-pyrimidine-4-carboxyl-ato)bis-(?(2)-pyrimidine-4-carboxyl-ato)tetra-kis-(aqua-lithium).

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(4)(H(2)O)(4)], contains two symmetry-independent Li(I) ions, two symmetry-independent ligands and two symmetry-independent coordinated water mol-ecules. They form a dinuclear unit in which the two Li(I) ions are bridged by two carboxyl-ate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetra-meric mol-ecule. One of the Li(I) ions shows a distorted tetra-hedral coordination geometry, the other a distorted trigonal-bipyramidal environment. The tetra-mers are held together by hydrogen bonds in which coordinated water mol-ecules act as donors, and the carboxyl-ate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.
