✦ Synopsis

From the reaction of isoor0tic and 2-thioisoorotic acids with Ag x, Pd ~I, PtII and Pt w ions, twelve new complexes containing the uracil ligand in either mono-or dianionic forms have been isolated and studied by conductivity measurements, i.r. and n.m.r, spectroscopies, and by thermal methods (t.g. and d.s.c.). From the data obtained, tentative molecular structures are suggested for each complex. The most common coordination mode of both acids involves formation of a six-membered chelate ring through the exocyclic 0(4) atom and an oxygen of the carboxylate group. The antimicrobial activity of these compounds against several bacteria and yeast has also been assayed. It is noticeable that PdCI(HzCU ). py complex is active against Pseudomonas Sp. and Micrococcus sp. at MIC values lower than 50 ~tgcm -3.
