Two Ferrocene Acid And Double-sulfonic Acid Functional Synthesis And Characterization Of Complexes

Currently, coordination chemistry has been a most important field in the research of modern chemistry and also has a closely contact with modern physics, life, material, and environment science. At the same time, it gets in touch with the other subordinate subjects in chemistry and this leads to many new cross-subjects. It has been widely used in industry and living, such as tonnages, petrochemistry, and catalysts. Coordination chemistry should promote the development the chemistry in 21 century. As the living comparison, which was put forward by famous chemist-Xu Guangxian, said that if 21 century could be considered as a human being, the physical chemistry, theoretic chemistry, and quantum chemistry should be looked as head, analytical chemistry should be looked as ears and eyes, coordination chemistry should be looked as heart, inorganic chemistry is left hand, organic chemistry and macromolecular chemistry must be right hand, material science ought to be right leg, and life science must be left leg.In the paper, a series of ferrocenyl complexes have been reported, including six polymers of l,l'-ferrocenyldisulphonates (1-6) and five coordination compounds of l,l'-ferrocenyldisuccinic acids (7-11). It is well known that 1,1'-ferrocenyldisulphonates have been applied in the decoration of electro rods and new style surfactant. Meanwhile, considering the similarities of the structure and the properties between phosphonates and sulphonates, both of them can be employed to synthesis of porous materials, which are widely used in the research of catalysts and absorbents, by the result of their multiple coordination knots and many coordination modes. It can be clearly seen from the crystal structures of polymers 1-6 that they have not only micro pores, but also micro pores, so this kind materials can be used as the supplementary of molecular sieves and must have significant help to improve the catalysis efficiency. It should be pointed out that only the oxygen donors in polymer 6 coordinated to control metal ions, and give rise to a 2D sandwich-like framework, while in the others structures, the solvent aqua have take place of ligand l,l'-ferrocenyldisulphonates to coordination to transition metal atoms.Coordination compounds 7-11 were fabricated through the reaction ligand l,l'-ferrocenyldisuccinic acids with transition metals Zn, Co, Mn, Pb. Compounds 7-9 are 3D supramolecular which based on simple mononuclear coordination complexes. However, polymer 10 is a 1D infinite hinge-like chains structure by the interaction of π - π stacking and polymer 11 has a 2D network structure.Additionally, we also report two simple complexes and a octanuclear metal cluster [K₈O(FcCOO)₆] in this article. By the quantum calculation, we found that the eight K ions interacting strongly with each other the outer p orbitals, the Wiberg bond orders of K-K are K4-K7 0.0745, K5-K7 0.0961, K6-K7 0.0630, K78-K79 0.0745, K75-K79 0.0634, K76-K79 0.0961, and all of the K atoms contribute most to the frontier orbits. Also, we noticed that the Mullikin electron charge of central oxygen atom (O74) is by far larger than those of other oxygen atoms. We believe that the electron distribution of central oxygen is [core]2S²2p⁶, while that of the other is [core]2S²2p⁵. It indicates that the central oxygen atom interacts with K atoms through covalent bond, but the others depended on coordination bonds. The application of quantum calculation will explore a new way to check the stabilities of coordination compounds, especially of polynuclear metal clusters.
