New iron(III) nitrate hydrates: Fe(NO₃)₃·xH₂O with x = 4, 5 and 6

H. Schmidt, A. Asztalos, F. Bok and W. Voigt

Synopsis: The crystal structure of iron(III) trinitrate hexahydrate is built up from [Fe(H₂O)₆]²⁺ octahedra and nitrate anions connected via hydrogen bonds. In iron(III) trinitrate pentahydrate, one water molecule in the coordination octahedron of the Fe^III atom is substituted by an O atom of a nitrate group. Iron(III) trinitrate tetrahydrate represents the first example of a simple iron(III) nitrate with pentagonal-bipyramidal coordination geometry, where two bidentate nitrate anions and one water molecule form a pentagonal plane.

Formula: [Fe(H₂O)₆](NO₃)₃, [Fe(NO₃)(H₂O)₅](NO₃)₂ and [Fe(NO₃)₂(H₂O)₃]NO₃·H₂O

Lanthanum tetrazinc, LaZn₄

I. Oshchapovsky, V. Pavlyuk, G. Dmytriv and A. Griffin

Synopsis: The structure of LaZn₄ has been determined from single-crystal X-ray diffraction data for the first time, approximately 70 years after its first discovery. The structure is closely related to the BaAl₄, La₃Al₁₁, BaNi₂Si₂ and CaCu₅ structure types, which can be presented as close-packed arrangements of 18-vertex clusters, in this case LaZn₁₈.

Formula: LaZn₄
