SnMo2O8has been shown to exhibit very different phase behavior and thermal expansion from previously studied members of the AM2O8family.1At high temperatures, SnMo2O8, ZrW2O8, and ZrMo2O8assume cubic structures with orientationally disordered MO4tetrahedra; however, their behavior is widely divergent at lower temperatures. ZrMo2O8maintains its disordered structure and continues to display negative thermal expansion (NTE). While cubic symmetry is retained when cooling ZrW2O8, its WO4tetrahedra become ordered, and its NTE increases in magnitude. Rapid cooling of SnMo2O8leads to a cubic structure that only minimally differs from its high temperature form.1Slowly heating this cubic phase results in a transformation to a rhombohedral (γ) structure with ordered MoO4tetrahedra that is not isostructural to any known phases of ZrW2O8and ZrMo2O8.1In stark contrast to ZrW2O8, and ZrMo2O8, all SnMo2O8phases exhibit positive thermal expansion.1In the current work, the phase behavior and thermoelastic properties of cubic SnMo2O8under hydrostatic conditions were investigated via in situ synchrotron x-ray powder diffraction in a recently designed sample environment.2Previous studies of ZrW2O8and ZrMo2O8in this environment have shown that pressure-induced disordering of MO4tetrahedra, which only occurred in the orientationally ordered low temperature ZrW2O8phase, was linked to both elastic softening on heating and enhancement of NTE.3At 298K, cubic SnMo2O8is significantly softer (κT =30GPa) than ZrW2O8 (64GPa) and ZrMo2O8(43GPa).3Unlike ZrW2O8, which softens upon heating to 516K (ΔκT = -9GPa), SnMo2O8stiffens (+5GPa) more than ZrMo2O8(+2GPa).3The phase behavior of SnMo2O8under pressure also differs from that of ZrW2O8and ZrMo2O8. Compression elevated the γ->cubic transition temperature significantly: at ambient temperature, this transition occurs at ~435K; at 310MPa, it occurs at ~490K.
