Abstract
A new Pb(IV)-based coordination polymer having formula [(C6H5)(3)Pb-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 (tau(5) = 0.19) around the central Pb(IV) center. The aromatic pi-electron cloud is solely drifted to the anti-bonding sigma*-orbital of Pb-S bond thereby forming intramolecular Pb center dot center dot center dot C tetrel bonding interaction; intramolecular S center dot center dot center dot 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. (C) 2020 Elsevier B.V. All rights reserved.
