Abstract

Hydrothermal syntheses of single crystals of rare earth iodates, by decomposition of the corresponding periodate, are presented. This appears to be a generic method for making rare earth iodate crystals in a short period of time. Single crystal X-ray diffraction structures of the four title compounds are presented.
Sc(IO3)(3): Space group R(3), Z = 6, lattice dimensions at 100 K; a = b = 9.738(1), c = 13.938(1) Å; R-1 = 0.0383.
Y(IO3)(3) · 2H(2)O: Space group P(1), Z = 2, lattice dimensions at 100 K: a = 7.3529(2), b = 10.5112(4), c = 7.0282(2) Å, ? = 105.177(1)°, ? = 109.814(1)°, ? = 95.179(1)°; R-1 = 0.0421. La(IO3)(3) · ø H(2)O: Space group Pn, Z = 2, lattice dimensions at 100 K: a = 7.219(2), b = 11.139(4), c = 10.708(3) Å, ? = 91.86(1)°; R-1 = 0.0733.
Lu(IO3)(3) · 2H(2)O: Space group P(1), Z = 2, lattice dimensions at 120 K: a = 7.2652(9), b = 7.4458(2), c = 9.3030(3) Å, ? = 79.504(1)°, ? = 84.755(1)°; ? = 71.676(2)°; R-1 = 0.0349.
