✦ Synopsis

rhombic, Pnam, a = 7.842(1), b = 8.613(1), c = 24.407(2) A, V= 1648.5(5) A3, Z = 4, Dx = 3.299 g-cm"3, MoKa, X = 0.70930 A, (i= 75.7 cm"1, 77(000) = 1496, T=292 K, R = 0.030 for 3018 observed reflections with I> 3ct(7). The iodic acid and iodate groups are arranged in along the b- axis corrugated slabs with the HI03 molecules at the crests and troughs. The channels between them are extended along the a-axis and filled with Be(H20)4+ cations and water molecules. All the structural fragments take part in a H-bonding scheme.

Abstract All components of the linear electrooptical and of the piezooptical tensor of hexagonal Al(IO3)3 · 2HIO3 · 6H2O have been determined for He-Ne radiation at 6328 Å by static methods. The crystals possess large electrooptical constants r 113 and r 333. As both constants have the same sign, th
