Organometallic Chemistry under Hydro(solvo)thermal conditions: Synthesis and X-ray structure of (Ph_4P)_2[Mn_3(CO)_9(S_2)_2(SH)], (Ph_4P)[Mn_2(CO)_6(SH)_3], and (Ph_4P)_2[Mn_4(CO)_(13)(Te_2)_3]

摘要

Hydrothermal, or more generally, hydro(solvo)thermal syntheses may be defined as chemical reactions carried out in superheated water or organic solvents at sub-, near, or supercritical conditions. The rapid transport ability of the solvent under suchconditions often leads directly to crystal growth of the product similar to the formation of many mineral crystals in nature. Thus far, the hydro(solvo)thermal synthesis has found numerous applications in solid-state chemistry and materials science. Useof a similar concept to carry out organometallic reactions in sealed ampoules or autoclaves at elevated pressures and temperatures has opened up a new avenue for organometallic cluster chemistry. In this report, we describe three novel cluster compounds1-3, obtained from zethanothermal synthesis. The formation of these compounds provides insight into the reaction pathways dictated by the solvent under the solvothermal conditions.
