以4-氨基苯甲酸和1,10-菲啰啉(phen)与高氯酸铁或硝酸镉反应,得到了两个邻菲啰啉的配合物:[Fe(phen)3]·2Cl O4·2CH2OH(1)和[Cd(phen)2(NO3)2](2)。并利用元素分析、红外光谱和X射线单晶衍射分析进行了表征。晶体结构分析表明,配合物(1)和(2)晶体属单斜晶系,C2/c空间群,其晶胞参数分别为:(1)a=35.708(3),b=15.903(2),c=12.204(1),β=102.504(6),V=6766(1)3,Z=8。(2)a=11.6887(6),b=15.2569(8),c=13.4630(10),β=105.9650(10),V=2310.5(2)3,Z=4。配合物(1)中phen上的氢原子与来自高氯酸根和乙二醇的氧原子形成氢键,并且相邻phen的吡啶环之间形成π~π堆积,从而使整个晶体扩展为三维网状超分子结构;配合物(2)中phen上氢原子与硝酸根的氧原子之间通过氢键使整个晶体扩展为三维网状超分子结构。
The complexes of two phenanthrolines were obtained by the reaction of 4-aminobenzoic acid and 1,10-phenanthroline with iron perchlorate or cadmium nitrate: [Fe (phen) 3] · 2ClO4 · 2CH2OH (1) and [Cd (phen) 2 (NO3) 2] (2). And characterized by elemental analysis, infrared spectroscopy and X-ray single crystal diffraction analysis. The crystal structure analysis shows that the crystal structures of the complexes (1) and (2) are monoclinic and C2 / c space group. The unit cell parameters are as follows: a = 35.708 3 b = 15.903 2 ) , c = 12.204 (1) , β = 102.504 (6) , V = 6766 (1) 3, Z = 8. (2) a = 11.6887 (6) , b = 15.2569 (8) , c = 13.4630 (10) , β = 105.9650 (10) , V = 2310.5 (2) 3, Z = 4. The hydrogen atom on phen in the complex (1) forms hydrogen bonds with the oxygen atoms from perchlorate and ethylene glycol, and the π-π stacking between the pyridine rings in adjacent phen forms the whole crystal into a three-dimensional network Shaped supramolecular structure; the hydrogen atom on the phen atom in the complex (2) and the oxygen atom in the nitrate atom expand the entire crystal into a three-dimensional network of supramolecular structures by hydrogen bonding.
