Effect of the Crystallization Temperature and the N-donor Ligand Nature on the Crystal Structure of {EuCd} Complexes with Pentafluorobenzoic Acid Anions
Variation of the crystallization temperature of cadmium pentafluorobenzoate {[Cd(H2O)4(pfb)](pfb)}n (Hpfb = pentafluorobenzoic acid), europium pentafluorobenzoate [Eu2(H2O)8(pfb)6]·2H2O, and pyrazino[2,3-f][1,10]phenanthroline (pzphen) in MeCN results in the isolation of crystals: coordination polymer [Eu2(H2O)2Cd2(pzphen)2(pfb)10]n (1) at 25 °C and [Eu2Cd4(pzphen)4(pfb)14]n·4nMeCN (2) and [Eu2Cd2(pzphen)4(pfb)10]·10MeCN (3) compounds at 75 °C. When bathophenanthroline (bphen) and 2,9-dimethylbathophenanthroline (mbphen) are used as N-donor ligands, the crystallization temperature does not affect the compositions and structures of the compounds formed, and therefore, [Eu2Cd2(bphen)2 (pfb)10]n·2nMeCN (4) and [Eu2Cd2(mbphen)2(pfb)10]·H2O (5) complexes are formed. The synthesized compounds are characterized by single crystal X-ray diffraction, IR spectroscopy, and the CHN analysis. The structures and crystal packings of the obtained complexes are examined in detail. The main contribution to the stabilization of crystal packings is made by π⋯π, C–H⋯F, C–F⋯π interactions.
期刊介绍：
Journal is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond; the use of physical methods to study the electronic and spatial structure of chemical species; structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials; and the crystal structure of solids.
