A series of neutral homologous complexes [(L)Ln(Cy 3 PO)Cl] {where Ln = Gd ( 1 ), Tb ( 2 ), Dy ( 3 ), and Er ( 5 )} and [(L)Dy(Ph 3 PO)Cl] ( 4 ) [H 2 L = 2,6-diacetylpyridine bis -benzoylhydrazone] were isolated. In these complexes, the central lanthanide ion possesses a pentagonal bipyramidal geometry with an overall pseudo D 5 h symmetry. The coordination environment around the lanthanide ion comprises of three nitrogen and two oxygen donors in an equatorial plane. The axial positions are taken up by a phosphine oxide (O donor) and a chloride ion. Among these compounds, the Dy(III) ( 3 and 4 ) analogues were found to be field-induced single-ion magnets.
