The synthesis of the new Co(II), Ni(II), Cu(II), Cd(II), Pd(II) and Pt(II) complexes with 1-methyllumazine (1-methylpteridine2,4(1H ,3H )-dione, MLM) and 1,6,7-trymethyllumazine (1,6,7-trimethylpteridine-2,4(1H ,3H )-dione, MLMD) is described. The coordination chemistry of these ligands have been investigated and an usual bidentate bonding mode through the N5 and O4 atoms is observed. These com...
