✦ Synopsis

Large single crystals of the polar lithium sulfamate, Li[NH 2 SO 3 ], were grown from aqueous solution. The crystal structure was determined using single crystal X-ray diffraction data (space group: Pca2 1 (Nr. 29), a=16.253(2) Å, b=5.0529(3) Å, c=8.2469(7) Å, R=0.019). Precise refractive indices were measured in the wavelength region between 0.36 µm and 1.53 µm. Above λ ≈ 0.85 µm Li[NH 2 SO 3 ] shows optic uniaxial behaviour. A phase-matched optical second harmonic generation is not possible. Measurements of temperature dependence of thermal expansion and of main birefringences ∆n (i) have given no hints for structural phase transitions in the investigated temperature region (from -130 °C to +25 °C).

The crystal structure of Li(C 6 H 7 O 7 ) ´H2 O has been determined by single-crystal X-ray diffractometry. It crystallizes in the triclinic space group P 1 with Z = 2. The structure was solved by direct and Fourier methods and refined to R1 = 0.031. Some comparisons with related struc-tures are mad
