Materials Data on BiS4N3Cl4 by Materials Project
N3S4BiCl4 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two N3S4 clusters and one BiCl4 ribbon oriented in the (1, 0, 0) direction. In each N3S4 cluster, there are three inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a bent 150 degrees geometry to two S2- atoms. Both N–S bond lengths are 1.58 Å. In the second N+2.33+ site, N+2.33+ is bonded in a bent 150 degrees geometry to two S2- atoms. There is one shorter (1.55 Å) and one longer (1.57 Å) N–S bond length. In the third N+2.33+ site, N+2.33+ is bonded in a bent 150 degrees geometry to two S2- atoms. There is one shorter (1.54 Å) and one longer (1.56 Å) N–S bond length. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a bent 120 degrees geometry to two N+2.33+ atoms. In the second S2- site, S2- is bonded in a bent 120 degrees geometry to two N+2.33+ atoms. In the third S2- site, S2- is bonded in a single-bond geometry to one N+2.33+ atom. In the fourth S2- site, S2- is bonded in a distorted single-bond geometry to one N+2.33+ atom. In the BiCl4 ribbon, Bi5+ is bonded to six Cl1- atoms to form edge-sharing BiCl6 octahedra. There are a spread of Bi–Cl bond distances ranging from 2.55–3.06 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent Bi5+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent Bi5+ atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Bi5+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Bi5+ atom.
