Monoclinic-trigonal transition in some MI3M′III(XO4)3 compounds: The high temperature form of (NH4)3In(SO4)3

Hydrothermal synthesis and crystal structures of two NLO compounds, NaIO3·H2O and In(IO3)3

“…5. The octahedral geometry around the In 3+ center is slightly distorted, with the 180 • octahedral angles being 171.36 (12) • , and the 90 • octahedral angles in the range 84.33(10)-96.26(12) • ( Table 3) [15]. The magnitude of the In off-center displacement (0.005Å for In(IO 3 ) 3 ) is somewhat smaller than that observed for the Al atoms in Al(IO 3 ) 3 (0.023Å) [5], consistent with the general observation that distortions around cations M 3+ (M = Al, Ga, In) decrease with increasing cation size.…”
