Abstract: In the structure of [Cu(ClO₄)₂(PA)₂(-phen)]·PA [PA = pyridine-4-carboxaldehyde oxime or 4-pyridinealdoxime (C₆H₆N₂O) and phen = 1,10-phenanthroline (C₁₂H₈N₂)], the coordination geometry around the Cu^II atom may be described as a distorted octahedron. Four N atoms, two from a phen ligand and two from PA ligands, occupy the equatorial positions, while two O atoms from two perchlorate groups occupy the axial positions. The PA molecules which are not involved in the Cu^II coordination link the complexes through O-HN and O-HO hydrogen bonds, forming layers parallel to the ac plane.
