LiNa₅Mo₉O₃₀

Abstract

The tite compound, lithium penta­sodium nona­molybdate, LiNa5Mo9O30, was synthesized by solid-state reaction. The three-dimensional [Mo9O30]6− framework is built up from MoO6 octa­hedra and MoO5 bipyramids, linked together by edges and corners. The framework delimits two types of inter­secting tunnels running along [100] and [010] in which the Na+ and Li+ ions are located. The asymmetric unit contains one Mo, one Na and one Li site located on a twofold rotation axis. The crystal studied was a racemic twin with site a twin ratio of 0.51 (10):0.49 (10). Relationships between the structures of K2Mo3O10, K2Mo4O13, Cs2Mo7O22, Na6Mo10O33 and Na6Mo11O36 compounds are discussed.

LiNa5Mo9O30: Crystal Growth, Linear, and Nonlinear Optical Properties

“…A well-polished high-quality (001) wafer of LiNa 5 Mo 9 O 30 has a LDT of ~ 1.2 GW/cm 2 which is comparable with other well-known NLO crystals (see Table 1). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 20 We collected single crystal data on a small piece of one of our grown crystals and did not observe any racemic twinning.…”

“…There is a relatively long bond, ∼2.547(7) Å, between Mo(2) and O(13) (see Table S1). In the Hamza et al work, Mo­(i)–O bonds longer than 2.5 Å were neglected, and the structure of LiNa 5 Mo 9 O 30 was described containing MoO 6 octahedra and MoO 5 pyramids . Bond valence sums (BVS) , of the cations were calculated and are listed in Table S2.…”

“…In this paper we report on the high quality and large crystal growth (centimeter size crystals) of LiNa 5 Mo 9 O 30 and its associated optical - linear and nonlinear - properties. LiNa 5 Mo 9 O 30 was first reported by Hamza et al during their attempt to replace one Na + with Li + in Na 6 Mo 11 O 36 . In the Hamza et al work, the main focus was on solving and refining the crystal structure which had a racemic twin issue.…”
