Mono sodium 2,4,6-trioxotetrahydropyrimidine-1(2H)-carbodithioate (L) was prepared from These compounds were characterized using infra-red spectra FTIR, electronic spectra UV-VIS, proton nuclear magnetic resonance 1 H-NMR spectroscopy, Micro Elemental Analysis, and Magnetic Measurements.These measurements indicate that the prepared complexes have octahedral, square planer or tetrahedral geometry. Molar Conductance measurements shows all the prepared complexes are non-electrolytic except the palladium complex of the type [Pd(L)(H2O)2]Cl.

Two silver nanoparticles containing compounds were prepared by simple chemical reactions and characterized by X-ray diffraction (XRD), infra-red spectrum (FTIR) and atomic force microscope (AFM). These functionalized silver nanoparticles were used to study their biological activity against four types of fungi. These compounds proved to have high inhibition effect against all types of studied fungi. Due to the presence of silver nanoparticles which increases nystatin and clotrimazol interact with the fungi.
