A symmetrical Σ=13 [001] {510} tilt grain boundary is studied by High Resolution Electron Microscopy and statics molecular relaxation. From the experimental images and the geometry of the different basic models, a new type of grain boundary is proposed. The {510} interface is not made up of a periodic structure, but of a mixture of slightly different basic structures, i.e. the interface is composed of a constant part and a variable core where some atoms have several stable positions.
