“…These compounds crystallize in a number of different structure types, for example fluorite-type structures (δ-Bi 2 O 3 -based complex oxides [1]), layered Aurivillius type structures (the BIMEVOX family [2]) or unique columnar structures (Bi 26 Mo 10 O 69 [3]). The latter is reported to contain [Bi 12 O 14 ] ∞ columns oriented along the y-axis, MoO n polyhedrons and «isolated» Bi 3+ ions [4]. Bi 26 Mo 10 O 69 exhibits pure one-dimensional oxide ion transport along the columnar fragments (y axis) [5].…”

“…The structure of the triclinic form with one additional oxygen position was suggested in [7]. It includes MoO 5 [8]; Co [9]; V, P, W [6], while, larger cations can be substituted for bismuth including Pb [10]; Ln [11]; Ca, Sr, Ba [6] and Mn [12]. It was shown previously that the best conductivity properties of Bi 26-2x X-ray powder diffraction (XRPD).…”

Single phase samples of bismuth molybdate, Bi26Mo10O69, doped with Mn on the bismuth sublattice and V, Fe on the molybdenum sublattice were found to crystallize in the triclinic Bi26Mo10O69 structure at low doping levels and in the monoclinic Bi26Mo10O69 structure - at higher dopant concentration. The assumption that all Mn ions have an oxidation state of +2 was confirmed by means of magnetic measurement results analysis using Curie-Weiss law. Conductivity was investigated using impedance spectroscopy. The conductivity of Bi26.4Mn0.6Mo9.6Fe0.4O69-d was 1.2*10-2 S*cm-1 at 973 K and 2.2*10-4 S*cm-1 at 623 K, and the conductivity of Bi26.4Mn0.6Mo9.2V0.8O69-d was 2.2*10-3 S*cm-1 at 973 K and 2.2*10-5 S*cm-1 at 623 K.
