Popis:	The interaction of some trace metal ions with a chemical mutagen 5-bromouracil (5-BrU) has been studied spectroscopically and by magnetic measurements. 5-BrU is coordinated to the Mn(II), Ni(II), and Cu(II) ions through the N atom of N(1)H group and the O atom of C(4)=O group whereas to the Co(II), Zn(II), and Cd(II) ions through O atom of C(4)=O group only. The new complexes except Co(II) complex which are insoluble in water and other common organic solvents involve polymeric structures. The tentative νM–O and νM–N band assignments in the lower region favor coordination number six for all complexes.
