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.
