摘要：
Rare earth basic nitrate hydrates (LnBN) of the general formula [Ln(6)(mu(6)-O)(mu(3)-OH)(8)(H2O)(12)(eta(2)-NO3)(6)] (NO3)(2)center dot xH(2)O, (Ln = Y, Sm, Eu, Gd. Tb, Dy, Ho, Er, Tm, Yb, Lu; x = 3, 4, 5, 6) exist at least in seven different structure types (A(1)-D). The present paper describes and discusses their synthesis and structure determination. The basal building unit, common to all these compounds, is a [Ln(6)(mu(6)-O)(mu(3)-OH)(8)(H2O)(12)(eta(2)-NO3)(6)](2+) cluster of idealized symmetry -32/m. The stoichiometry is completed by non-coordinated (NO3)(1-) anions and H2O molecules in interstices. (C) 2009 Elsevier B.V. All rights reserved.
