The relaxor ferroelectric Pb 2 Bi 4 Ti 5 O 18 has been studied by Rietveld refinement of powder neutron diffraction data collected at temperatures of 100, 250 and 400 1C. Our refinements are compatible with the 'average' crystal structure of Pb 2 Bi 4 Ti 5 O 18 undergoing the phase transition sequen
