Molecular structure design and synthetic approaches to the heterometallic alkoxide complexes (soft chemistry approach to inorganic materials by the eyes of a crystallographer).
TL;DR: The molecular structure design approach based on the choice of a proper molecular structure type and completing it with the ligands, providing both the necessary number of donor atoms and the sterical protection of the metaloxygen core, is presented.

The effect of a magnetic field on a RAPET (reaction under autogenic pressure at elevated temperature) of MoO(OMe)4: Fabrication of MoO2 nanoparticles coated with carbon or separated MoO2 and carbon particles
Swati V. Pol,Vilas G. Pol,Vadim G. Kessler,Gulaim A. Seisenbaeva,M.‐G. Sung,S. Asai,Aharon Gedanken +6 more
TL;DR: Results of the RAPET dissociation of MoO(OMe)4 at 700 degrees C in a closed Swagelok cell are presented and it produces a mixture of comparatively larger (50 nm) molybdenum dioxide nanoparticles and separated uncoated carbon particles.

Molybdenum and tungsten (VI) bimetallic alkoxides. Decomposition accompanied by dialkylether elimination
TL;DR: In this paper, the existence of (1:1) bimetallic complexes in alcohol solutions has been proved by conductometric titration curves of MO(OR)4, and MO2 (OR)2 (M = Mo, W; R = Et, iPr, C2H4OMe) by sodium (or lithium) alkoxides.
