Multiferroic materials represent a topic of current interest in solid state physics. In order to understand the multitude of phenomena occurring in these materials the issue of quadrupolar ordering has attracted a lot of interest. Here, a model system to study and understand quadrupolar ordering phenomena is required. PrB6, with its simple crystal structure and well known magnetic structure, is a suitable material to act as such a model system. In this contribution, we present a detailed study of the low-temperature structural properties of PrB6. By means of high-resolution x-ray diffraction we find the first direct experimental proof of a structural lattice distortion in PrB6, and which seems to be driven by its magnetic phase transition.
