Tetra-kis(?-3,4-dimethoxy-phenyl-acetato)bis-[(3,4-dimethoxy-phenyl-acetato)(1,10-phenanthroline)dysprosium(III)].

ABSTRACT: The title centrosymmetric dinuclear dysprosium(III) complex, [Dy(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)] or [Dy(L)(3)phen](2), is comprised of six 3,4-dimethoxy-phenylacetate (L) anions, two 1,10-phenanthroline (phen) mol-ecules and two Dy(III) ions. The Dy(III) atom is nine-coordinated by seven O atoms from five L ligands and two N atoms from the phen mol-ecules. The L ligands are coordinated to the Dy(III) ion in three coordination modes: chelating, bridging and bridging-tridentate. C-H?O hydrogen bonding interactions consolidate the crystal packing.

Project description:In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H⋯O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions and weak aromatic π-π inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821 (2) Å].

Project description:In the title centrosymmetric dinuclear complex, [Tm(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the unique Tm(III) ion is coordin-ated by five 3,4-dimethoxy-phenyl-acetate (DMPA) ligands and and a bis-chelating 1,10-phenanthroline (phen) ligand via seven O atoms and two N atoms, forming a distorted tricapped trigonal-prismatic environment.

Tetra-kis(μ-phenoxy-acetato-κO:O')bis-[(1,10-phenanthroline-κN,N')manganese(II)] methanol hemisolvate.

Project description:The title complex, [Mn(2)(C(8)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·0.5CH(3)OH, is a carboxyl-ate-bridged dinuclear Mn(II) complex with four phenoxy-acetate ions and two 1,10-phenanthroline mol-ecules as ligands. Each of the four phenoxy-acetate anions bridges the pair of Mn atoms. The asymmetric unit is completed by a half-occupancy methanol solvent mol-ecule. Face-to-face π-π stacking inter-actions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn(2) complexes, with an inter-planar separation of circa 3.4 Å, and weak C-H⋯O hydrogen bonds connect the dinuclear units into a three-dimensional supra-molecular framework.

Bis(3,4-dimethoxy-benzoato-?O,O')(1,10-phenanthroline-?N,N')copper(II).

Project description:The asymmetric unit of the title compound, [Cu(C(9)H(9)O(4))(2)(C(12)H(8)N(2))], contains one half-mol-ecule, the complete mol-ecule being generated by a twofold rotation axis. The Cu(II) atom exhibits a six-coordinated distorted octa-hedral geometry with two N atoms from the phenanthroline ligand [Cu-N 2.007?(2)?Å] and four O atoms from two 3,4-dimethoxy-benzoate ligands [Cu-O 1.950?(1) and 2.524?(1)?Å]. The difference in Cu-O bond distances indicates a strong Jahn-Teller effect. In the crystal, C-H?? inter-actions result in chains of mol-ecules along the c axis.

Project description:In the dimeric centrosymmetric title complex, [Er(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Er(III) ion is nine-coordinated by five 2-(3,4-dimeth-oxy-lphen-yl)acetic acid (DMPA) ligands via seven O atoms and two N atoms from a bis-chelating 1,10-phenanthroline (phen) ligand in a distorted tricapped trigonal-prismatic geometry. The DMPA ligands are coordinated to the Er(III) ion in bis-chelate, bridging and bridging tridentate modes. Relatively weak intra-molecular C-H?O inter-actions reinforce the stability of the mol-ecular structure. Inter-molecular C-H?O inter-actions are also observed.

Bis(1,10-phenanthroline-?N,N')(phenyl-acetato-?O)copper(II) phenyl-acetate hexa-hydrate.

Project description:In the title compound, [Cu(C(8)H(7)O(2))(C(12)H(8)N(2))(2)](C(8)H(7)O(2))·6H(2)O, the Cu atom is in a distorted square-pyramidal coordination environment. The six crystallographically independent uncoordinated water mol-ecules are inter-connected by hydrogen bonds, completing dodeca-water (H(2)O)(12) clusters which are hydrogen bonded to the carboxyl-ate groups of phenyl-acetate anions, building up one-dimensional anionic chains propagating along [100]. Between the cationic and anionic chains are hydrogen bonds from water mol-ecules to the carboxyl-ate O atoms belonging to the phenyl-acetato ligands.

Tetra-kis(μ-naphthalene-1-acetato-1:2κO:O')bis-(naphthalene-1-acetato)-1κO,O';2κO,O'-bis-(1,10-phenanthroline)-1κN,N';2κN,N'-europium(III)samarium(III).

Project description:In the title compound, [EuSm(C(12)H(9)O(2))(6)(C(12)H(8)N(2))(2)], the metal site is statistically occupied (50:50) by Eu and Sm atoms, forming a centrosymmetric complex. The metal site is nine-coordinate, in a distorted monocapped square-anti-prismatic coordination geometry. Mol-ecules are linked into three chains by C-H⋯π interactions and C-H⋯O hydrogen bonds. The combination of these chains generates a three-dimensional framework structure. One of the bridging naphthalene-1-ace-tate ligands was found to be disordered over two sites; the site occupancies for the naphthylmethyl group refined to 0.628 (14) and 0.372 (14).

Project description:In the title compound, [Cu(CH(3)CO(2))(C(12)H(8)N(2))(2)](CF(3)CO(2))·4H(2)O, the Cu(II) atom shows a distorted octa-hedral coordination with four N atoms [Cu-N = 2.015 (3)-2.244 (3) Å] from the two phenanthroline ligands and two O atoms from the acetate [Cu-O = 1.953 (3) and 2.764 (3) Å]. Strong inter-molecular O-H⋯O hydrogen-bonding inter-actions consolidate the crystal packing. The F atoms of the anion are disordered over two positions in a 0.5233 (3):0.4767 (3) ratio.
