Abstract: The interactions of Co(II), Ni(II), Cu(II), Cd(II), Mg(II) and Ca(II) with nicotinic acid (nicH2) and Cytosine (cytH2) were studied and also several alkaline earth metal and transition metal compounds were studied by FT-IR (Fourier Transform Infrared) Spectroscopy. Some alkaline earth metal–nicotinic acid–cytosine ternary compounds were formed and the structure of the [M (nic)(cyt)(H2O)] ternary complex resolved. Each metal (II) atom has a distorted trigonal bipyramid coordination which is linked to a water molecule, a cytosine via N(3), a carboxylic oxygen atom of a nicotinic acid moiety and two bridging di co-ordinated nicotinates bound through the carboxylic oxygen atoms & pyrimidine nitrogen atoms. To these five main bonds, two interactions can be observed the second oxygen of the mono co-ordinated nicotinate group and the carboxylic oxygen of the cytosine ligand. The compound is stabilized by an intramolecular stacking between the pyrimidine and cytosine rings and by the hydrogen bonds between the coordinated water molecules and the ligands.
