Crystal structural study of ternary molybdate LiRbBi2(MoO4)4

Crystal chemistry and topology of Rb–MIII molybdates (M = Fe, Sc, In) and triclinic Rb2Mo4O13: novel building blocks, decorated chains and layers

“…The structure shows a layered arrangement ( Fig. 1 X-ray powder diffraction data of the a-modification of Rb 5 Fe(MoO 4 ) 4 (quenched from 520 C) are given in The compound Rb 5 In(MoO 4 ) 4 is isotypic with Rb 5 Er(MoO 4 ) 4 (Klevtsova, Glinskaya, 1976). The asymmetric unit contains one In site, three Rb, two Mo and eight oxygen sites.…”

“…. It is noteworthy that the crystal structure data for Rb 5 Er(MoO 4 ) 4 reported by Klevtsova and Glinskaya (1976) are presently missing in the ICSD. According to the detailed classification of M Lazoryak and Efremov (1987), Rb 5 In(MoO 4 ) 4 adopts structure type VII, which is related to type V characterised by zigzag chains.…”

Phase relations in the system K2MoO4–KPO3–MoO3–Bi2O3: A new phosphate K3Bi5(PO4)6

“…4a). This is an unusual assemblage of bismuth polyhedra in oxide compounds and was observed for the first time in LiRbBi 2 (MoO 4 ) 4 [29]. This connection between two neighboring rings through the common Bi 12 circles is given in Fig.…”

A potential red-emitting phosphors scheelite-like triple molybdates LiKGd2(MoO4)4:Eu3+ for white light emitting diode applications

“…Basovich et al [6] reported an abundant family of triple molybdates of LiMLn 2 (MoO 4 ) 4 that existed along the LiLn(MoO 4 ) 2 -MLn(MoO 4 ) 2 section in the Li 2 MoO 4 -M 2 MoO 4 -Ln 2 (MoO 4 ) 3 (M = K, Tl, Rb) systems. LiKGd 2 (MoO 4 ) 4 and triple bismuth molybdates LiMBi 2 (MoO 4 ) 4 (M = K, Tl, Rb) [7] are isostructural, and also they are similar to the double and triple molybdates of BaLn 2 (MoO 4 ) 4 and Li 3 Ba 2 Ln 3 (MoO 4 ) 8 [8] in construction. LiKGd 2 (MoO 4 ) 4 compound has a scheelite-like layered structure.…”
