Benzene tricarboxylic acid (BTC) is a common ligand molecule for MOF synthesis. Its structure affects MOF propagation and structure. To study the effect an additional chelating unit will have on MOF structure, phenol tricarboxylic acid (PTC) was used to synthesize MOF compounds based on transition metals (Co-,Ni- and Zn) and lanthanides (La-, Eu-, Tb-, and Nd). These new MOF compounds are of 2D (transition metals), and 3D (lanthanides) structures. These structures are different than BTC based MOF compounds due to the additional hydroxyl unit of the PTC ligand molecule. Characterization of the synthesized MOF compounds and structure analysis suggests these as promising candidates for applications as gas storage materials, optics\luminescence devices and others.
