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

ABSTRACT: 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.

Project description:The title complex, [Cu(2)(C(16)H(10)NO(2))(4)(CH(3)OH)(2)], consists of centrosymmetric wheel-shaped dinuclear neutral mol-ecules in which each Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by four O atoms of carboxyl-ate groups from different ligands at the basal plane and an O atom of a methanol mol-ecule at the axial position. In the crystal, the dinuclear complex mol-ecules are linked into one-dimensional supra-molecular columns parallel to the b axis by O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.7259?(11)?Å].

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

Project description: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.

The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen bonds.

Hexa-?2-chlorido-?4-oxido-tetra-kis[(morpholine-?N)copper(II)] methanol disolvate.

Project description:In the title solvate, [Cu4(?2-Cl)6(?4-O)(C4H9NO)4]·2CH3OH, each Cu(2+) ion in the tetra-nuclear complex has a trigonal-bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central ?4-O(2-) ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N-Cu bonds in equatorial orientations. In the crystal, the components are linked by N-H?O and O-H?O and O-H?Cl hydrogen bonds, which generate a three-dimensional network. One methanol mol-ecule is disordered over two sets of sites in a 0.642?(9):0.358?(9) ratio.

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.

Tetra-kis(1,10-phenanthroline)bis-(?-pyridine-2,6-dicarboxyl-ato)(pyridine-2,6-di-carboxyl-ato)dicopper(II)terbium(III) nitrate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Cu(2)Tb(C(7)H(3)NO(4))(3)(C(12)H(8)N(2))(4)]NO(3)·4H(2)O, consists of one-half of the C(2)-symmetric trinuclear coordination cation, one-half of the C(2)-symmetric nitrate anion and two water mol-ecules. In the coordination cation, the Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging-chelating carboxyl-ate group of the pyridine-2,6-dicarboxyl-ate anion, completing a distorted N(4)O(2) octa-hedral coordination environment. The Tb(III) atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate anions forming an N(3)O(6) donor set. The intra-molecular Cu?Tb distance of 5.0592?(11)?Å indicates weak inter-actions between the Cu(II) and Tb(III) atoms. The coordination cations, nitrate anions and water mol-ecules are connected via O-H?O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive ?-? stacking inter-actions [centroid-centroid distances = 4.332?(7) and 3.878?(5)?Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxyl-ate ligands.

Project description:In the mononuclear title compound, [Co(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·2C(3)H(7)NO·2H(2)O, the Co(II) atom, which lies on a center of inversion, is coordinated by four water mol-ecules and two N atoms from two two symmetry-related 1H-benzimidazole-5,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry. The packing is governed by inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions.

cyclo-Tetra-kis(μ-3-acetyl-4-methyl-1H-pyrazole-5-carboxyl-ato-κN,O:N,O)tetra-kis[aqua-copper(II)] tetra-deca-hydrate.

Project description:The title compound, [Cu(4)(C(7)H(6)N(2)O(3))(4)(H(2)O)(4)]·14H(2)O, a tetra-nuclear [2 × 2] grid-type complex with S4 symmetry, contains four Cu(II) atoms which are bridged by four pyrazole-carboxyl-ate ligand anions and are additionally bonded to a water molecule. Each Cu(II) atom is coordinated by two O atoms of the carboxyl-ate and acetyl groups, two pyrazole N atoms of doubly deprotonated 3-acetyl-4-methyl-1H-pyrazole-5-carb-oxy-lic acid and one O atom of a water mol-ecule. The geometry at each Cu(II) atom is distorted square-pyramidal, with the two N and two O atoms in the equatorial plane and O atoms in the axial positions. O-H⋯O hydrogen-bonding interactions additionally stabilize the structure. One of the uncoordinated water molecules shows half-occupancy.
