“…KMo 4 O 6 , for instance, crystallizes in two modifications, a highpressure polymorph in P4/mbm as well as a slightly distorted variant in Pbam stable at ambient temperature and pressure. Superstructure formation by vacancy ordering in space group Pbam was reported for Ba 0.62 Mo 4 O 6 by Torardi & McCarley (1981) or in space group P4/mnc for Pb 0.75 Mo 4 O 6 (Wang & Yeh, 1991). NMR experiments indicated that NaMo 4 O 6 itself may be incommensurately modulated and that a lowtemperature phase transition occurs at ca 140 K (Chu & Gerstein, 1989).…”

The (3 + 1)-dimensional modulated crystal structure of the metal-rich cluster compound InMo4O6 was solved and refined from single-crystal data in the superspace group P4/mbm(00γ)00ss [q = 0, 0, 0.1536 (4); a = 9.6664 (9), c = 2.8645 (3) Å; R1(all) = 0.046, wR(all) = 0.076]. The crystal structure is closely related to the NaMo4O6 structure type. It is built from rods of Mo6 clusters condensed via trans edges. These form channels parallel to [001], in which In6 and In7 oligomers alternate. Weak diffuse planes parallel to (001)* interconnect the satellite reflections; they occur due to two-dimensional rod disorder of the In oligomer chains.

A new two‐step procedure for the synthesis of MoS2 nanotubes using lead as a growth promoter is reported. In the first step, molybdenum suboxide nanowhiskers containing a small amount of lead atoms were created by exposing a pressed MoS2+Pb mixture to highly compressed shock‐heated argon gas, with estimated temperatures exceeding 9900 K. In the second step, these molybdenum suboxide nanowhiskers served as templates for the sulfidization of the oxide into MoS2 nanotubes (by using H2S gas in a reducing atmosphere at 820 °C). Unlike the case of WS2 nanotubes, the synthesis of a pure phase of MoS2 nanotubes from molybdenum oxide has proven challenging, due mostly to the volatile nature of the latter at the high requisite reaction temperatures (>800 °C). In contrast, the nature and apparent reaction mechanism of the method reported herein are amenable to future scale‐up. The high‐temperature shockwave system should also facilitate the synthesis of new nanostructures from other layered materials.
