Materials Data on Au3N3(Cl6O)2 by Materials Project

(AuCl4)4(AuN2(OCl2)2)2N2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four ammonia molecules, eight AuCl4 clusters, and four AuN2(OCl2)2 clusters. In each AuCl4 cluster, Au3+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are a spread of Au–Cl bond distances ranging from 2.30–2.34 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Au3+ atom. In each AuN2(OCl2)2 cluster, Au3+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. All Au–Cl bond lengths are 2.31 Å. N+2.33+ is bonded in a distorted single-bond geometry to one O2- and one Cl1- atom. The N–O bond length is 1.13 Å. The N–Cl bond length is 2.48 Å. O2- is bonded in a single-bond geometry to one N+2.33+ atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to one Au3+ and one N+2.33+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom.

Materials Data on Au3N3(Cl6O)2 by Materials Project

AuCl4Au2N(OCl4)2N2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight ammonia molecules, four Au2N(OCl4)2 clusters, and four AuCl4 clusters. In each Au2N(OCl4)2 cluster, Au3+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are a spread of Au–Cl bond distances ranging from 2.30–2.43 Å. N+2.33+ is bonded in a linear geometry to two equivalent Cl1- atoms. Both N–Cl bond lengths are 2.08 Å. O2- is bonded in a single-bond geometry to one Cl1- atom. The O–Cl bond length is 1.53 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to one Au3+ and one N+2.33+ atom. In the second Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to one Au3+ and one O2- atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In each AuCl4 cluster, Au3+ is bonded in a square co-planar geometry to four Cl1- atoms. There are two shorter (2.30 Å) and two longer (2.31 Å) Au–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Au3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Au3+ atom.
