| It is widely concerned through a rational choice of transitional metal ions and ligands containing N atoms of coordination polymers, which is constructed. Coordination chemistry has become the intersection of many disciplines and practical application of research focus, because of its valence bond form and spatial structure in the chemical bonding theory, development, and its relationship with the physical chemistry, organic chemistry, biochemistry, solid-state chemistry, materials chemistry and environmental chemistry of the mutual penetration, it will also further expand its use in electronic, optical, magnetic chemistry, catalysis and biological simulation broad application prospects in many fields. What's more, it is by eitherπ-πstacking interactions or intermolecular and intramolecular hydrogen bond casued by 1,10 - phenanthroline and 2,2'- bipyridine nitrogen-containing aromatic system, many supramolecular coordination polymers with new structures and special functions can be assembled. So, non-linear optical materials, magnetic materials, superconducting materials and catalysis and many other fields have shown an attractive prospect. At the meantime, pyrophosphate ion as a polydentate ligand multi-core polymer formed as a multi-functional materials can be acted as a template agent. It has a bright application prospect for pyrophosphate in the laser matrix, ceramics, electrical, magnetic, contact responses. Therefore, synthesis and structure of containing pyrophosphate– bridged ligands are increasingly drawn the attentions of the scientific research workers. For these reasons, we use Mo, Cu, Mn and Ni as the metal center to synthesize five kinds of different novel coordination polymer structure ( 1) [Cu2 (phen) 2 (H2O) 2] P2O7 ? 8H2O (2) [Mo (Phen) O2F2] (3) [Mn (Phen) 3] ? [(PO4) (H2O)] 3 (4) [Cu (Phen) 2 (H2O) 2] ? [(ClO4) (H2O)] (5) [Ni2 (Phen) 6] ? (ClO4) 4. And by the use of SHELXTL programs analytic structure, we can determine the five kinds of complex structures. |
