Materials Data on Ag2Au3N6Cl17 by Materials Project
Au3Ag2Cl13(N2)2(NCl2)2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of eight ammonia molecules; four dichloramine molecules; and two Au3Ag2Cl13 ribbons oriented in the (1, 0, 0) direction. In each Au3Ag2Cl13 ribbon, there are two inequivalent Au5+ sites. In the first Au5+ site, Au5+ is bonded in a square co-planar geometry to four Cl1- atoms. There are two shorter (2.32 Å) and two longer (2.33 Å) Au–Cl bond lengths. In the second Au5+ site, Au5+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are two shorter (2.30 Å) and two longer (2.33 Å) Au–Cl bond lengths. Ag2+ is bonded in a 5-coordinate geometry to five Cl1- atoms. There are a spread of Ag–Cl bond distances ranging from 2.60–3.26 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Au5+ atom. In the second Cl1- site, Cl1- is bonded in a linear geometry to two equivalent Ag2+ atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Au5+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Au5+ and two equivalent Ag2+ atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted linear geometry to one Au5+ and one Ag2+ atom.
