Abstract

Inorganic chemistry is essential to the formulation and improvement of modern materials such as catalysts, semiconductors, optical devices, super conductors, and advanced ceramic materials.1 New areas of inorganic chemistry are constantly being explored and new and often unusual inorganic compounds are constantly being synthesized and identified.1 Recently the field of inorganic chemistry has witnessed the synthesis and characterization of microporous metal organic framework compounds (MOFs). Microporous organic/inorganic materials have a wide range of physical properties as well as applications. The physical properties and applications drive the investigation into the synthesis and discovery of new and useful hybrid MOF materials. The defining character of these compounds is their porosity, however, in many cases no effort was made to show evidence that a stable porous structure has been achieved and that the pores may be accessed.2 The scope of this research will focus on developing the chemistry of metal organic framework materials of the general type M(II)/tetrazolate, where M is a first row transition element and tetrazolate is a type of organic ligand. The design of organic-inorganic hybrid materials conceives of the metal or metal cluster as a node from which rigid or flexible multitopic organic ligands radiate to act as tethers to adjacent nodes in the bottom-up construction of complex extended molecular architectures.3 The synthesis of organic-inorganic hybrid materials is conducted under hydrothermal conditions varying the organic ligand, the inorganic node, and the temperature. Utilizing the microporous species synthesized, an attempt is made to show evidence that a stable porous structure has been achieved and that the pores may be accessed. Thermal gravimetric analysis, nitrogen adsorption isotherm, hydrogen uptake isotherm, and physical dimensions of the crystal [Co2(HBDT)3]•20H2O and (CH3NH2)[Cu4Cl(tba)4(H2O)4]•20H2O are the physical methods employed in this research. The three-dimensional structures and physical properties of [Co2(HBDT)3]•20H2O and (Me2NH2)[Cu4Cl(tba)4(H2O)4]•15H2O are reported.
