Bis(acetato-κ2O,O′)(di-2-pyridyl-κN-amine)copper(II) dihydrate

The copper(II) ion in the title complex, [Cu(C2H3O2)(2)(C10H9N3)].2H(2)O, is coordinated unsymmetrically to each of the two bidentate acetate ligands and to the N atoms of the di-2-pyridyiamine (dpyam) ligand. The copper(II) ion is surrounded by a distorted square-based arrangement of the two dpyam pyridyl N atoms at distances of 1.974(2) and 1.995(2) Angstrom, and by two acetate O atoms at distances of 1.965(1) and 1.967(1) Angstrom. The second O atom from each acetate group is involved in weak coordination in the tetragonal positions, at longer Cu-O distances of 2.482(2) and 2.690 (2) Angstrom, completing the six-coordination. The overall geometry at the copper(II) ion is best described as distorted octahedral with elongated axial bonds.
