Structural studies of nanocluster materials recently carried out in INEOS, are reviewed. Metal nanoclusters in polymer matrices (Co, Pt, Pt/Pd, etc.), as well as Pd blacks formed by oxidative aggregation of stoichiometric Pd clusters in organic media and binary nanoparticles (MoS2 composites obtained via monolayer dispersions, coated nanocrystallites of TiO2 anatase) were characterized. Laboratory and synchrotron X-ray diffraction data, together with local structural parameters taken from XAFS spectroscopy and the results of XRD simulation using model atomic arrangements, revealed type and distortions of atomic packing. Published single crystal X-ray structural data for big stoichiometric clusters extracted from Cambridge Structure Database (CSD) were represented as new 2D polar histograms and used as references.
