Four low-temperature phases with compositions Bi{sub 10}Mo{sub 3}O{sub 24}, Bi{sub 6}Mo{sub 2}O{sub 15}, Bi{sub 14}Mo{sub 5}O{sub 36} and Bi{sub 8}Mo{sub 3}O{sub 21} have been prepared by the n-butylamine wet synthesis method. They have been characterized by powder X-ray diffraction and transmission electron microscopy, mainly by selected area electron diffraction. The four phases present a close structural relationship and a common basic fluorite-type structure and are members of a homologous series of phases with general formula Bi{sub 2n+4}Mo{sub n}O{sub 6(n+1)}, being n=3, 4, 5 and 6, respectively. The matrices relating their superstructures and the basic fluorite type unit cell are given, as well as a general one for the whole series. The conductor behavior of these phases is characterized by impedance spectroscopy being all these materials very good ionic conductors. - Graphical abstract: Four new phases Bi{sub 10}Mo{sub 3}O{sub 24}, Bi{sub 6}Mo{sub 2}O{sub 15}, Bi{sub 14}Mo{sub 5}O{sub 36} and Bi{sub 8}Mo{sub 3}O{sub 21} have been synthesized, characterized and described as consecutive members of a new family Bi{sub 2n+4}Mo{sub n}O{sub 6(n+1)}, with n=3, 4, 5 and 6. They are based on basic fluorite-type structure and their unit cells are depicted in the accompanying graphic.
