The Role of 2-Hydroxypyridine in the Formation of Pivalate Zn–Gd Complexes
The reactions of [Zn(Piv)2]n and [Gd(Piv)3]n or Gd(NO3)3∙6H2O with 2-hydroxypyridine (Hhp) or its 6-methyl derivative (Hmhp) afford heterometallic complexes [ZnGd(Рiv)5(Hhp)2]·0.5H2O (I), [Zn2Gd(Рiv)6(Hhp)2NO3]∙2C6H6 (II), [Zn3GdO(Рiv)7(Hmhp)2]∙MeCN (III), and [Zn2Gd(Рiv)6-(Hmhp)2NO3]∙0.5MeCN (IV), respectively. In the carboxylate metal cage of the synthesized complexes, the Hhp and Hmhp molecules in the form of 2-pyridone are coordinated by the metal atoms via the monodentate mode through the oxygen atoms. The introduction of Et3N into the reaction with [Zn(Рiv)2]n, Gd(NO3)3∙6H2O, and Hhp is found to result in the formation of compound [Zn4Gd2(OH)2-(Рiv)6(hp)6(Hhp)2] (V) in which the 2-hydroxypyridine anions perform the bridging function. The molecular structures of complexes I‒V are determined by XRD (CIF files CCDC nos. 2365419–2365423).
期刊介绍：
Russian Journal of Coordination Chemistry is a journal that publishes reviews, original papers, and short communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry is an interdisciplinary science that makes a bridge between inorganic, organic, physical, analytical, and biological chemistry.
