Modulated crystal structure of InMo4O6

Abstract

The (3 + 1)-dimensional modulated crystal structure of the metal-rich cluster compound InMo4O6was solved and refined from single-crystal data in the superspace groupP4/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 NaMo4O6structure type. It is built from rods of Mo6clusters condensedvia transedges. These form channels parallel to [001], in which In6and In7oligomers alternate. Weak diffuse planes parallel to (001)* interconnect the satellite reflections; they occur due to two-dimensional rod disorder of the In oligomer chains.
