A new 1D coordination polymer of triphenyl lead hydrosulfide: Synthesis and insights into crystal architecture and Hirshfeld surface analyses

Abstract

A new Pb(IV)-based coordination polymer having formula [(C6H5)3Pb-SH]n (1) has been synthesized and characterized using microanalyses, multinuclear NMR and single crystal X-ray diffraction. The X-ray crystal structure reveals a distorted square pyramidal geometry (τ5 = 0.19) around the central Pb(IV) center. The aromatic π-electron cloud is solely drifted to the anti-bonding σ*-orbital of Pb–S bond thereby forming intramolecular Pb⋯C tetrel bonding interaction; intramolecular S⋯H interaction also occurs in the linear chain of 1. The observed interactions have been discussed in detail and have been addressed critically by Hirshfeld surface analysis and fingerprint plots.
