Abstract

Varying the temperature of the reaction of [{Cd(pfb)(HO)}·(pfb)], [Ln(pfb)(HO)]·HO (Hpfb = pentafluorobenzoic acid), and 1,10-phenanthroline (phen) in MeCN followed by crystallization resulted in the isolation of two type of products: 1D-polymers [LnCd(pfb)(phen)]1.5MeCN (Ln = Eu (I), Gd (II), Tb (III), Dy (IV)) which were isolated at 25 °C, and molecular compounds [TbCd(pfb)(phen)] (V) formed at 75 °C. The transition from a molecular to a polymer structure becomes possible because of intra- and intermolecular interactions between the aromatic cycles of phen and pfb from neighboring tetranuclear LnCd fragments. Replacement of cadmium with zinc in the reaction resulted in molecular compounds LnZn [LnZn(pfb)(phen)]·4MeCN (Ln = Eu (VI), Tb (VIII), Dy (IX)) and [GdZn(pfb)(HO)(phen)]·4MeCN (VII). A new molecular EuCd complex [EuCd(pfb)(phen)]·4MeCN (X)] was isolated from a mixture of cadmium, zinc, and europium pentafluorobenzoates (Cd:Zn:Ln = 1:1:2). Complexes II-IV, VII and IX exhibit magnetic relaxation at liquid helium temperatures in nonzero magnetic fields. Luminescent studies revealed a bright luminescence of complexes with europium(III) and terbium(III) ions.

摘要

在乙腈中改变[{Cd(pfb)(HO)}·(pfb)]、[Ln(pfb)(HO)]·HO（Hpfb = 五氟苯甲酸）和1,10 - 菲咯啉（phen）的反应温度，然后进行结晶，得到了两种类型的产物：在25°C下分离得到的一维聚合物[LnCd(pfb)(phen)]1.5MeCN（Ln = Eu (I)、Gd (II)、Tb (III)、Dy (IV)），以及在75°C下形成的分子化合物[TbCd(pfb)(phen)]（V）。由于相邻四核LnCd片段中phen和pfb的芳环之间的分子内和分子间相互作用，从分子结构向聚合物结构的转变成为可能。在反应中用锌取代镉，得到分子化合物LnZn [LnZn(pfb)(phen)]·4MeCN（Ln = Eu (VI)、Tb (VIII)、Dy (IX)）和[GdZn(pfb)(HO)(phen)]·4MeCN（VII）。从五氟苯甲酸镉、锌和铕的混合物中分离出一种新的分子铕镉配合物[EuCd(pfb)(phen)]·4MeCN（X）。配合物II - IV、VII和IX在液氦温度下于非零磁场中表现出磁弛豫。发光研究揭示了含有铕(III)和铽(III)离子的配合物发出明亮的光。
