Thermal gravimetric analysis of equimolar silver(I) acetylacetonate-platinum(II) acetylacetonate mixture shows a significant increase in thermal stability of silver(1) acetylacetonate in the presence of the Pt counterpart. The heated mixture was examined by differential scanning calorimetry and complementary analyses of gaseous products, residues and sublimed fractions by Fourier transform infrared, Raman and X-ray-photoelectron spectroscopy, X-ray diffraction and scanning and high-resolution transmission electron microscopy. It is assumed that silver(I) acetylacetonate is thermally stabilized due to a week bonding with Pt chelate. An interaction between both chelates gets support from the structure of the residual powder which is composed of Ag, Pt, C and O elements and Pt oxides and contains silver nanoparticles whose decreased unit cell parameter can be due to substitution of silver by platinum
