Coordination Trends of 6-Amino-4-hydroxy-2-mercaptopyrimidine Towards Co (II), Ni (II) and Cu (II) Ions

Co(11) Ni(II) and Cu(II) complexes of 6-amino-4 hydroxy-2-mercaptopyrimidine have been prepared and characterized by several physiochemical tools in terms CHNS elemental analyses infrared electronic mass and proton nuclear magnetic resonance spectroscopy and molar conductivity measurements The CHNS elemental analysis data showed the formation of 1 1 [M L] ratio The infrared spectral data exhibited the complexation behavior of the ligand towards to metal ions which is through -NH2 SH and CN groups The electronic spectra displayed the existence of pi ->pi* and n ->pi* transitions The mass spectral data revealed the possible fragmentations of the ligand The proton nuclear magnetic resonance data of the ligand showed the position of the groups which enter in coordination The molar conductivity measurements showed that all complexes are non-electrolyte
