Description
Summary:A series of the cadmium and zinc carboxylate complexes with anions of pentafluorobenzoic (HРfbz) and 2,3,4,5-tetrafluorobenzoic (HТfbz) acids and N - donor ligands (1,10-phenanthroline (Phen) and quinoline (Quin)), [Cd(Pfbz) 2 (Phen)] n ( I ), [Cd(Рfbz) 2 (Рhen) 2 ]·2MeCN ( II ), [Zn(H 2 O)-(Рfbz) 2 (Рhen)] ( III ), [Zn 2 Cd(Рfbz) 6 (Рhen) 2 ]⋅2C 6 H 6 ( IV ), [Cd 2 (H 2 O) 2 (Tfbz) 4 (Рhen) 2 ] ( V ), [Cd 2 -(H 2 O) 2 (Tfbz) 4 (Quin) 2 ] ( VI ), and [Cd(Tfbz) 2 (Phen) 2 ]⋅HTfbz ( VII ), is synthesized. The structures of new complexes I – VII are determined by X-ray diffraction analysis (CIF files CCDC nos. 1871300, 2005461, 2005462, 2005464, 2005466, 2005465, and 2005459, respectively). The majority of the synthesized compounds is typical of intramolecular stacking interactions between the coordinated molecules of the aromatic N - donor ligands and fluorinated substituents of the carboxylate anions. These interactions lead to the formation of unusual compounds, which are different in the cases of pentafluorobenzoates and tetrafluorobenzoates, in particular, coordination polymer I and binuclear complexes V and VI with coordinated water molecules. The synthesized zinc and cadmium compounds differ in structure and composition.
