Synthesis and Characterization of MOF Compound Based on Azide (N3-) and Nicotinamide ligands with Cd(II),[Cd3(?-N3-)4(Nicotinamide)2]H2O

This work mainly based on azido complex an nicotinamide as coligand. Compound is characterized with X-ray Single Crystal Analysis, and IR spectroscopy. In compound (1) each cadmium centre shows distorted octahedral geometry. Each cadmium ion is surrounded by four nitrogen atoms of azide ligands at equatorial position and two nitrogen atoms of nicotinamide molecules axially. The N3 ligand connects to the Cd (II) atom in end-to-end bridging fashion. Each molecule is associated with one uncoordinated water molecule. This lattice uncoordinated water molecule is involved in hydrogen bonding with oxygen atom of amide group from nicotinamide molecules and gives additional strength to the structure.
