Abstract

NaHf3(NCl)3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Na is bonded to six Cl atoms to form NaCl6 octahedra that share corners with six HfN4Cl3 trigonal pyramids, edges with three equivalent NaCl6 octahedra, and edges with six HfN4Cl3 trigonal pyramids. All Na–Cl bond lengths are 2.80 Å. There are two inequivalent Hf sites. In the first Hf site, Hf is bonded to four N and three Cl atoms to form distorted HfN4Cl3 trigonal pyramids that share corners with two equivalent NaCl6 octahedra, edges with two equivalent NaCl6 octahedra, and edges with nine HfN4Cl3 trigonal pyramids. The corner-sharing octahedral tilt angles are 3°. There are a spread of Hf–N bond distances ranging from 2.11–2.13 Å. There are one shorter (2.93 Å) and two longer (2.96 Å) Hf–Cl bond lengths. In the second Hf site, Hf is bonded to four N and three Cl atoms to form distorted HfN4Cl3 trigonal pyramids that share corners with two equivalent NaCl6 octahedra, edges with two equivalent NaCl6 octahedra, and edges with nine HfN4Cl3 trigonal pyramids. The corner-sharing octahedral tilt angles are 3°. There are a spread of Hf–N bond distances ranging from 2.11–2.13 Å. There are one shorter (2.93 Å) andmore »« less
