Abstract
A new strategy for the construction of a microporous material is to use inorganic clusters as secondary building units in the assembly of the extended networks. We have already reported the synthesis and characterization of many metallamacrocycles with the modulation of the acyl side chain of a pentadentate ligand, N-acylsalicylhydrazide (H3xshz) and the construction of porous framework with the metallamacrocycle as SBU’s and using an exobidentate ligand, bis-pyridylethane (bpea) to construct a three-dimensional framework. We have synthesized N-acetylaminobenzhydrazide (H3aahz) a chelating pentadentate ligand like N-acetylsalicylhydrazide (H3ashz), with a simple difference of an -NH2 group instead of -OH group on the phenyl ring. We also have synthesized new hexanuclear metallamacrocycle using aahz3-. This metallamacrocycle was used as SBU to develop a new two-dimensio! nal network. The coordinated solvent of the metallamacrocycle was exchanged by bpea, which serve as linker to create two-dimensional network. Characterization of the new hexanuclear metallamacrocycle and two-dimensional network will be discussed.
