Report of the Double-Molybdate Phase Cs(2)Ba(MoO(4))(2) with a Palmierite Structure and Its Thermodynamic Characterization
[Image: see text] The existence of a novel double-molybdate phase with a palmierite-type structure, Cs(2)Ba(MoO(4))(2), is revealed in this work, and its structural properties at room temperature have been characterized in detail using X-ray and neutron diffraction measurements. In addition, its the...

description | [Image: see text] The existence of a novel double-molybdate phase with a palmierite-type structure, Cs(2)Ba(MoO(4))(2), is revealed in this work, and its structural properties at room temperature have been characterized in detail using X-ray and neutron diffraction measurements. In addition, its thermal stability and thermal expansion are investigated in the temperature range 298–673 K using high-temperature X-ray diffraction, leading to the volumetric thermal expansion coefficient α(V) ≈ 43.0 × 10(–6) K(–1). The compound’s standard enthalpy of formation at 298.15 K has been obtained using solution calorimetry, which yielded Δ(f)H(m)°(Cs(2)Ba(MoO(4))(2), cr, 298.15 K) = −3066.6 ± 3.1 kJ· mol(–1), and its standard entropy at 298.15 K has been derived from low-temperature (2.1–294.3 K) thermal-relaxation calorimetry as S(m)°(Cs(2)Ba(MoO(4))(2), cr, 298.15 K) = 381.2 ± 11.8 J K(–1) mol(–1). |
