Scheme of crystalline phases NaxFey(MoO4)z. The quarternary phases included are: (1) NaFe4(MoO4)5, (2) α-NaFe2(MoO4)3, (3) β-NaFe2(MoO4)3, (4) Na3Fe2(MoO4)3, (5) NaFe(MoO4)2, together with the ternary edge members (6) Fe2(MoO4), (7) β-Fe(MoO4), (8) Fe2(MoO4)3 and (9) Na2(MoO4). The coloured lines mark the ranges of composition with the same formal oxidation state m+ of Fe and n+ of Mo (blue: m = 2, n = 4; green: m = 3, n = 5; red: m = 2, n = 6; black: m = 3, n = 6). Only the region between the blue and black lines is of relevance for the orthomolybdate structures.
