Abstract

New trinuclear Cd–Ln molecular complexes [EuCd₂(O₂CC₆F₅)₆(NO₃)(Bipy)₂] (I, Bipy is 2,2'-bipyridine) and [LnCd₂(Bzo)₆(NO₃)(Phen)₂] · 4MeCN (Ln = Tb (II), Eu (III), Bzo is anion of 3,5-di-tert-butylbenzoic acid, Phen is 1,10-phenanthroline) are studied. Their structures are determined by X-ray structure analysis (СIF files CCDC nos. 1938125 (I), 1938124 (II)) or by X-ray diffraction analysis (III), and the photoluminescence properties are studied. The reactions of complexes I and II with terephthalic acid (H₂Bdc) are accompanied by the destruction of the heterometallic molecules to form 2D coordination polymers [Cd₃(Bbdc)₃(Bipy)₂]_3n · 4nMeCN · nH₂O (IV) and [Cd₂(Bdc)₂(Phen)₂]_n · 2nDMF (V) (СIF files CCDC nos. 1938126 and 1937492, respectively).

摘要

新的三核Cd-Ln分子复合物[EuCd ₂（O ₂ CC ₆ F ₅）₆（NO ₃）（Bipy）₂ ]（I，Bipy是2,2'-联吡啶）和[LnCd ₂（Bzo）₆（NO ₃）（Phen）₂ ]·4MeCN（Ln = Tb（II），Eu（III），Bzo是3,5-二叔丁基苯甲酸的阴离子，Phen是1,10-菲咯啉）。它们的结构通过X射线结构分析（СIF文件CCDC No. 1938125（I），1938124（II））或通过X射线衍射分析（III），并研究了光致发光特性。配合物I和II与对苯二甲酸（H ₂ Bdc）的反应伴随有杂金属分子的破坏，从而形成2D配位聚合物[Cd ₃（Bbdc）₃（Bipy）₂ ] _{3 n} ·4 n MeCN· n H ₂ O（IV）和[Cd ₂（Bdc）₂（Phen）₂ ] _n ·2 n DMF（V）（分别由IF文件CCDC编号1938126和1937492组成）。
