Abstract

Pt2C4NI8(C)2C2N crystallizes in the orthorhombic Ima2 space group. The structure is one-dimensional and consists of four aziridine molecules; eight methane molecules; and two Pt2C4NI8 ribbons oriented in the (0, 1, 0) direction. In each Pt2C4NI8 ribbon, there are two inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in an octahedral geometry to six I1- atoms. There are a spread of Pt–I bond distances ranging from 2.65–2.79 Å. In the second Pt2- site, Pt2- is bonded in a square co-planar geometry to four I1- atoms. There are a spread of Pt–I bond distances ranging from 2.57–2.64 Å. There are two inequivalent C+2.25+ sites. In the first C+2.25+ site, C+2.25+ is bonded in a bent 150 degrees geometry to one C+2.25+ and one I1- atom. The C–C bond length is 1.25 Å. The C–I bond length is 1.98 Å. In the second C+2.25+ site, C+2.25+ is bonded in a distorted single-bond geometry to one C+2.25+ and one N3- atom. The C–N bond length is 1.26 Å. N3- is bonded in a bent 150 degrees geometry to two equivalent C+2.25+ atoms. There are seven inequivalent I1- sites. In the first I1- site, I1- is bonded in an L-shaped geometry to two Pt2- atoms. In the second I1- site, I1- is bonded in an L-shaped geometry to two Pt2- atoms. In the third I1- site, I1- is bonded in a single-bond geometry to one Pt2- atom. In the fourth I1- site, I1- is bonded in a single-bond geometry to one Pt2- atom. In the fifth I1- site, I1- is bonded in a single-bond geometry to one Pt2- atom. In the sixth I1- site, I1- is bonded in a single-bond geometry to one Pt2- atom. In the seventh I1- site, I1- is bonded in a trigonal non-coplanar geometry to one Pt2- and two equivalent C+2.25+ atoms.
