Structure of ?-RbIn(WO4)2

Vibrational Characteristics of the Alkali Metal–Indium Double MolybdatesMIn(MoO4)2and TungstatesMIn(WO4)2(M=Li, Na, K, Cs)

“…The trigonal, P3M m1 structure (with a"5.80, c"7.25 A s , and Z"1) exists in the 850-930°C temperature range (7,12,13). It was possible to freeze this high-temperature phase down to room temperature by putting hot sample into the water (13).…”

Local structure and EPR g factors for KAl(MoO4)2:Cr3+ and RbIn(MoO4)2:Cr3+ systems

“…KAl(MoO 4 ) 2 and RbIn(MoO 4 ) 2 crystals possess trigonal P3m1 symmetry with one molecule in the unit cell have been reported by Klevtsova et al [24,25]. When Cr 3+ ions is doped in KAl(MoO 4 ) 2 and RbIn(MoO 4 ) 2 , Cr 3+ ion will replace the host Al 3+ ion or In 3+ ion, respectively.…”

Vibrational Study of Phase Transitions in KIn(WO4)2

“…One sequence is realized in the rapidly quenched crystals having a trigonal structure near ambient temperature and the respective structural changes are similar to those for the other trigonal molybdates and tungstates. However, KIn(WO ) di!ers signi"cantly from all the other crystals since its hightemperature structure is of D B symmetry (9), not D B as reported for other members of this family of layered compounds (except of KFe(MoO ) ). The second sequence of phase transitions may be described as the transitions between the high-temperature trigonal D B (for KIn(WO ) ) or D B (for RbIn(MoO ) ) and the low-temperature D phases.…”
