Abstract [en]

Mr=123.00, orthorhombic, Cmcm, Z=4; at 120K, a=6.713 (7), b=12.669 (4), c=5.968 (5) Aring, V=507.7 (7) Aring 3; at 295K, a=6.8018 (4), b=12.7132 (9), c=5.9990 (4), V=518.75 (6) Aring 3; m.p.=303.1K, Dx=1.575 g cm -3 (295K), f(000)=256; X-ray data (Mo Kalpha, lambda=0.71069 Aring) have been collected at 120K; final wR( F2) values 0.064 from conventional spherical-atom refinement and 0.033 from deformation refinement. The deformation electron density of LiNO 3.3H 2O has been studied at 120K (new data) and 295K in order to compare static and dynamic deformation maps derived at two temperatures. A combination of X-ray and neutron data has been used both for the X- N and the multipolar expansion maps. The N-O bond peaks are elongated perpendicular to the molecular plane. The water molecules show well developed deformation features and the hydrogen-bond density is consistent with what is usually observed for medium-strong hydrogen bonds.
