Aqua-{4,4'-dimeth-oxy-2,2'-[pyridine-2,3-diylbis(nitrilo-methanylyl-idene)]-diphenolato}copper(II).

ABSTRACT: Mol-ecules of the title compound, [Cu(C(21)H(17)N(3)O(4))(H(2)O)], lie across a crystallographic mirror plane. The Cu(II) atom is five-coordinated in a distorted square-pyramidal environment by two phenolate O atoms and two imine N atoms of the tetra-dentate Schiff base anion in the basal plane and one water mol-ecule in the apical position. Because of symmetry, the pyridine N atom and the corresponding C atom at the 4-position of the pyridine ring are disordered. The crystal packing can be described as being composed of alternating layers stacked along [001]. Intra-molecular C-H?N and inter-molecular C-H?O and O-H?O hydrogen-bonding inter-actions, as well as C-H?? and ?-? stacking inter-actions [shortest centroid-centroid distance = 3.799?(8)?Å and inter-planar distance = 3.469?(2)?Å] are observed.

Project description:The asymmetric unit of the title compound, [Cu(C(21)H(24)N(2)O(4))]·H(2)O, comprises half of a Schiff base complex and a water mol-ecule. The Cu(II) atom, water mol-ecule and one C atom of the central propyl-ene segment are located on a twofold rotation axis. The geometry around the Cu(II) atom is distorted square-planar, supported by the N(2)O(2) donor atoms of the coordinating ligand. The dihedral angle between the symmetry-related benzene rings is 42.56?(19)°. In the crystal, O-H?O hydrogen bonds involving the water mol-ecule make an R(2) (1)(6) ring motif. Complex mol-ecules are linked into a chain along the c axis via C-H?O inter-actions.

Acetato(aqua){6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolato}cobalt(III) methanol disolvate.

Project description:In the title complex, [Co(C(18)H(18)N(2)O(4))(C(2)H(3)O(2))(H(2)O)]·2CH(3)OH, the Co(III) atom is hexa-coordinated by water and acetate groups in the axial positions and by the tetra-dentate Schiff base occupying equatorial positions. These axial bonds are longer than the equatorial bonds to the tetra-dentate Schiff base. Two mol-ecules form a dimer through strong hydrogen bonds from the coordinated water of one mol-ecule to the meth-oxy O atoms of an adjoining mol-ecule. There is extensive intra- and inter-molecular O-H?O hydrogen bonding between the coordinated water and acetate ligands and the methanol solvent mol-ecules. In addition, there are weak inter-molecular C-H?O inter-actions, which link the mol-ecules into a three-dimensional array.

Aqua-{4,4'-dibromo-6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}copper(II).

Project description:The title complex, [Cu(C(18)H(16)Br(2)N(2)O(4))(H(2)O)], lies on a crystallographic mirror plane with the Cu(II) ion coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand and one O atom from a water ligand in a slightly distorted square-pyramidal environment. The mirror plane, which coincides with the Cu-O(water) bond, imposes disorder of the atoms of the ethyl-ene group. In the crystal structure, inter-molecular O-H?O hydrogen bonds link complex mol-ecules into extended chains along [100].

Project description:The asymmetric unit of the title compound, [Cu(C(21)H(24)N(2)O(2))]·H(2)O, comprises half of a Schiff base complex and half of a water mol-ecule. The whole compound is generated by crystallographic twofold rotation symmetry. The geometry around the Cu(II) atom, located on a twofold axis, is distorted square-planar, which is supported by the N(2)O(2) donor atoms of the coordinating Schiff base ligand. The dihedral angle between the symmetry-related benzene rings is 47.5 (4)°. In the crystal, the water mol-ecule that is hydrogen bonded to the coordinated O atoms links the mol-ecules via O-H⋯O inter-actions into chains parallel to [001]. The crystal structure is further stabilized by C-H⋯π inter-actions, and by π-π inter-actions involving inversion-related chelate rings [centroid-centroid distance = 3.480 (4) Å].
