Materials Data on GaSe3N2Cl5 by Materials Project

Abstract

GaCl4N2Se3Cl crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four GaCl4 clusters and four N2Se3Cl clusters. In each GaCl4 cluster, Ga3+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Ga–Cl bond distances ranging from 2.19–2.23 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Ga3+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Ga3+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Ga3+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Ga3+ atom. In each N2Se3Cl cluster, there are two inequivalent N4+ sites. In the first N4+ site, N4+ is bonded in a bent 120 degrees geometry to two Se2- atoms. There is one shorter (1.73 Å) and one longer (1.76 Å) N–Se bond length. In the second N4+ site, N4+ is bonded in a bent 120 degrees geometry to two Se2- atoms. There is one shorter (1.75 Å) and one longer (1.80 Å) N–Se bond length. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted single-bond geometry to one N4+ atom. In the second Se2- site, Se2- is bonded in a distorted water-like geometry to one N4+ and one Cl1- atom. The Se–Cl bond length is 2.28 Å. In the third Se2- site, Se2- is bonded in a water-like geometry to two N4+ atoms. Cl1- is bonded in a single-bond geometry to one Se2- atom.
