Abstract
The synthesis of Co II , Cu II , Fe II and Zn II based coordination compounds using terephthalic acid BDC , tartaric acid DHB , and 4- hydroxybenzoic acid 4-HBA as ligands by a solvent-based and solvent-free methods were reported. Thermal studies of the complexes performed in the temperature range of 30 ºC-950 °C showed a 9.406% weight loss observed between 200 ºC-517 ºC for [Co DHB 4-HBA ] complex, and a 1.883 % weight loss observed between 80 ºC352.68 ºC for [Cu DHB 4-HBA ] complex.

Porous materials generally are solids which have pores in their frameworks which act as spaces that can accommodate other guest molecules [1]
Inorganic porous materials usually exhibit ordered frameworks and their synthesis often entails the use of inorganic or organic templates with strong interaction existing between the inorganic moiety and the template
Summary
Porous materials generally are solids which have pores in their frameworks which act as spaces that can accommodate other guest molecules [1]. Organic carbon (i.e. activated carbon) and zeolites (inorganic frameworks) are the commonly known porous materials. Activated carbon is known to have high surface areas and high adsorption capacities; it lacks an ordered structure. Despite this limitation, porous carbon materials have found applications in various processes which include storage of gases, shape and size-selective catalysis, and templates for low dimensional materials [2,3]. There is a lack of diversity in the earlier known inorganic frameworks due to the elements used being limited mostly to either Al or Si. Removal of the template sometimes results in the breakdown of the framework. These frameworks, have found applications in catalysis and molecular separations [1,3]
