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).
