Abstract

Nb16N9 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are eight inequivalent Nb sites. In the first Nb site, Nb is bonded in a linear geometry to two N atoms. Both Nb–N bond lengths are 2.22 Å. In the second Nb site, Nb is bonded to five N atoms to form corner-sharing NbN5 square pyramids. There are a spread of Nb–N bond distances ranging from 2.16–2.18 Å. In the third Nb site, Nb is bonded in a linear geometry to two N atoms. Both Nb–N bond lengths are 2.21 Å. In the fourth Nb site, Nb is bonded in a square co-planar geometry to four N atoms. There are two shorter (2.16 Å) and two longer (2.19 Å) Nb–N bond lengths. In the fifth Nb site, Nb is bonded in a T-shaped geometry to three N atoms. There are one shorter (2.21 Å) and two longer (2.23 Å) Nb–N bond lengths. In the sixth Nb site, Nb is bonded in a rectangular see-saw-like geometry to four N atoms. There are a spread of Nb–N bond distances ranging from 2.16–2.19 Å. In the seventh Nb site, Nb is bonded in a square co-planar geometry to four Nmore »« less
