Growth and Characterization of 4- Aminopyridinium Nickel II Chloride

In recent years, layered hybrid organic–inorganic compounds based on metal halide units have attracted much attention due to their possibility to combine the properties of organic and inorganic materials at the molecular level [1]. In fact, organic compounds offer a number of useful properties, including structural diversity, mechanical plasticity and ease of processing [2]. Inorganic materials have a distinct set of advantages, including good electric mobility, tunable band gap property, magnetic property and thermal stability [3,4]. In these materials, the structural arrangement can be described as an alternation of inorganic sheets and layers of the organic molecules. The nature of the interface has been used to grossly divide these materials into two distinct classes. In class I, organic and inorganic compounds are embedded and only weak bonds (hydrogen, van der waals or meson forces) give the cohesion to the whole structure. In class II materials, the two phases are linked together through strong chemical bonds (covalent or iono-covalent bonds).
