Abstract

Nb12I21Br crystallizes in the orthorhombic Pcc2 space group. The structure is three-dimensional. there are six inequivalent Nb sites. In the first Nb site, Nb is bonded to five I atoms to form a mixture of distorted edge and corner-sharing NbI5 square pyramids. There are a spread of Nb–I bond distances ranging from 2.88–3.01 Å. In the second Nb site, Nb is bonded to four I and one Br atom to form distorted NbI4Br square pyramids that share a cornercorner with one NbI4Br square pyramid and edges with four NbI5 square pyramids. There are two shorter (2.88 Å) and two longer (2.90 Å) Nb–I bond lengths. The Nb–Br bond length is 2.86 Å. In the third Nb site, Nb is bonded to five I atoms to form a mixture of distorted edge and corner-sharing NbI5 square pyramids. There are a spread of Nb–I bond distances ranging from 2.87–3.02 Å. In the fourth Nb site, Nb is bonded to five I atoms to form a mixture of distorted edge and corner-sharing NbI5 square pyramids. There are a spread of Nb–I bond distances ranging from 2.88–3.01 Å. In the fifth Nb site, Nb is bonded to five I atoms to form a mixturemore »« less
