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

ABSTRACT: 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.

Project description:The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand and seven O atoms from six phenoxy-acetate ligands. The coordination geometry at the Pr(III) atom is distorted tricapped trigonal prismatic. One phenyl ring is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Chlorido(chloro-difluoro-acetato-κO)bis(1,10-phenanthroline-κN,N')manganese(II).

Project description:The chloride and chloro-difluoro-acetate anions occupy cis positions in the octa-hedral coordination geometry of the title compound, [Mn(C(2)ClF(2)O(2))Cl(C(12)H(8)N(2))(2)]. The two N-heterocycles both chelate the metal atom.

Dichlorido(methanol-κO)[2-(2-pyridyl-meth-oxy)-1,10-phenanthroline-κN,N',N'']manganese(II).

Project description:In the title mononuclear complex, [MnCl(2)(C(18)H(13)N(3)O)(CH(4)O)], the Mn(II) ion assumes a distorted octa-hedral geometry. There is a π-π stacking inter-action between the phenanthroline ligand and the pyridine ring of a neighboring complex [centroid-to-centroid distance 3.5518 (13) Å]. The crystal structure also contains weak inter-molecular O-H⋯Cl hydrogen bonds that link neighboring complex mol-ecules into a one-dimensional chain along the b axis.

Aqua-bis(dichloro-acetato-κO)(1,10-phenanthroline-κN,N')copper(II).

Project description:In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichloro-acetate ligand occupies the apical positon [Cu-O = 2.152 (3) Å]. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing also exhibits weak inter-molecular C-H⋯O hydrogen bonds, π-π inter-actions [centroid-centroid distance = 3.734 (2) Å] and short inter-molecular Cl⋯Cl contacts [3.306 (2) and 3.278 (2) Å].

(Croconato-κO,O')bis-(1,10-phenanthroline-κN,N')manganese(II).

Project description:The title complex, [Mn(C(5)O(5))(C(12)H(8)N(2))(2)], lies across a crystallographic twofold axis which passes through the Mn atom and bisects the croconate ligand. The two 1,10-phenanthroline (phen) ligands are arranged in a propeller manner and the local mol-ecular geometry of the MnN(4)O(2) unit is severely distorted octa-hedral. This may be inter-preted as a structural perturbation of the MnN(4) square by the croconate ligand. In the crystal structure, the dipole moments of the mol-ecules are arranged alternately along the +b and -b directions. All the phen ligands are involved in π stacking inter-actions, alternately along the [110] and [10] directions. The alternate spacings between the neighbouring phen planes in the one-dimensional π stacks are 3.361 (2) and 3.526 (2) Å.

Weak inter-molecular C-H⋯O inter-actions link neighbouring mol-ecules.

4,7-Diphenyl-1,10-phenanthroline methanol hemisolvate.

Project description:The asymmetric unit of the title compound, C24H16N2·0.5CH3OH, is comprised of two independent bathophenanthroline mol-ecules (systematic name: 4,7-diphenyl-1,10-phenanthroline) and one methanol mol-ecule. The bathophenanthroline mol-ecules are not planar as there is a considerable rotation of all terminal phenyl rings with respect to the central phenanthroline units [dihedral angles in the range 52.21 (12)-62.14 (10)°]. In addition, a non-negligible torsion is apparent in one of the phenanthroline units: the angle between the mean planes of the two pyridine rings is 14.84 (13)°. The methanol solvent mol-ecule is linked to both N atoms of a bathophenanthroline mol-ecule through a bifurcated O-H⋯(N,N) hydrogen bond.

Project description:In the crystal structure of the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))](n), the Mn(II) atoms are linked by nitrate ligands to form a chain.

In the crystal structure, the chains are linked by hydrogen bonds into a polymeric ribbon structure.
