Study of solid/liquid and solid/gas interfaces in Cu-isoleucine complex by surface X-ray diffraction

► Surface atomic structure of Cu(Ile)2 complex with N2 gas and a supersaturated Cu(Ile)2 solution. ► Intensity variation along CTRs shows modifications at the atomic surface structure. ► Surface signal are compared with the ideal bulk and with the relaxed structure. ► The packing conditions influence the atomic structure.
