Materials Data on Pb(SN)2 by Materials Project

Abstract

Pb(NS)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Pb(NS)2 clusters. Pb2+ is bonded in a 1-coordinate geometry to one N1+ and two equivalent S2- atoms. The Pb–N bond length is 2.27 Å. There are one shorter (2.78 Å) and one longer (2.93 Å) Pb–S bond lengths. There are two inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a bent 120 degrees geometry to two S2- atoms. There is one shorter (1.59 Å) and one longer (1.71 Å) N–S bond length. In the second N1+ site, N1+ is bonded in a bent 120 degrees geometry to one Pb2+ and one S2- atom. The N–S bond length is 1.52 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one N1+ atom. In the second S2- site, S2- is bonded in a bent 120 degrees geometry to two N1+ atoms.
