We performed anomalous small angle x-ray-scattering (ASAXS) experiments with synchrotron radiation to study the 3-dimensional nanostructures of three metal/organic hybrids formed by crosslinking Al/organic stabilized Pt-particles with different bifunctional organic spacer-molecules. The advantage of ASAXS is the possibility of separating the particle scattering from that of the organic components thus providing unbiased information on particle size distribution and interparticle correlation. In order to obtain the structural information from the scattering data use was made of A. Vrij's equations for a multicomponent system of hard spheres. The results indicate that the Pt-particles are successfully interconnected by the organic spacers. However, the degree of ordering between the particles is less pronounced due to a quite large polydispersity of the Pt-particles.
