A series of neutral homologous complexes [(L)Ln(CyPO)Cl] {where Ln = Gd (), Tb (), Dy (), and Er ()} and [(L)Dy(PhPO)Cl] () [HL = 2,6-diacetylpyridine -benzoylhydrazone] were isolated. In these complexes, the central lanthanide ion possesses a pentagonal bipyramidal geometry with an overall pseudo 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) ( and ) analogues were found to be field-induced single-ion magnets.
一系列中性同系配合物[(L)Ln(CyPO)Cl] {其中Ln = Gd ()、Tb ()、Dy ()和Er ()}以及[(L)Dy(PhPO)Cl] () [HL = 2,6 - 二乙酰基吡啶 - 苯甲酰腙]被分离出来。在这些配合物中，中心镧系离子具有五角双锥几何构型，整体具有近似 对称性。镧系离子周围的配位环境在赤道平面上由三个氮供体和两个氧供体组成。轴向位置由一个氧化膦（O供体）和一个氯离子占据。在这些化合物中，Dy(III)（ 和 ）类似物被发现是场诱导单离子磁体。
