The structure of Bi 2 Al 4 O 9 has been re5ned using a combination of X-ray and high-resolution neutron powder di4raction. Iterative simulation of the 27 Al MAS solid state NMR data con5rms the presence of two Al sites, one octahedral and one tetrahedral, in an approximate 1:1 ratio. The structure o
