Structure cristalline de la triple molybdate Ag(0.90)Al(1.06)Co(2.94)(MoO(4))(5)

Silver(I) aluminiun tricobalt(II) penta­kis­[tetra­oxidomolybdate(VI)], Ag(0.90)Al(1.06)Co(2.94)(MoO(4))(5), was synthesized using a solid-state reaction at 845 K. The structure can be described as a three-dimensional framework formed from dimeric M (2)O(10) (M = Co/Al) and trimeric M (3)O(14) units...

Sumario:Silver(I) aluminiun tricobalt(II) penta­kis­[tetra­oxidomolybdate(VI)], Ag(0.90)Al(1.06)Co(2.94)(MoO(4))(5), was synthesized using a solid-state reaction at 845 K. The structure can be described as a three-dimensional framework formed from dimeric M (2)O(10) (M = Co/Al) and trimeric M (3)O(14) units linked to MoO(4) tetra­hedra by sharing corners, with the cavities occupied by disordered Ag(+) cations. It is shown that the Co and Al atoms occupy common positions with different occupancies. The Ag(+) cations are located at two different sites with occupancies of 0.486 (1) and 0.408 (1). The title coumpond is isotypic with NaMg(3)Al(MoO(4))(5) and NaFe(4)(MoO(4))(5). Differences and similarities with other related structures are discussed.
