<p>The current investigation presents two new crystal structures of organotin complexes, R₂SnCl₂ (<b>1</b>) and [R₂Sn(µ-S)]₂ (<b>2</b>), where R is 2-acetamido-5-methyl phenyl. This research aims to integrate O → Sn intramolecular coordination via an unexplored functionalization on organotin center. The complexes are crystallized in a triclinic system, specifically within the P-1 space group. The asymmetric unit of complex <b>2</b> is comprised of two identical R₂SnS units. The Sn center in both complexes displays a distorted octahedral geometry. The observed elongation of the Sn–O bond upon complexation indicates weaker intramolecular coordination in <b>2</b> (2.59&#xa0;Å) compared to <b>1</b> (2.22&#xa0;Å). Complex <b>2</b> exhibits various intermolecular interactions including N–H···O and N–H···S in their supramolecular assembly. Hirshfeld surface is generated for complex <b>2</b> to study the reactive surfaces of the complex. 2D fingerprint plots revealed the major contributions in crystal packing of <b>2</b> are C···C (0.2%), C···H/H···C (20.2%), O···H/H···O (10.6%), S···H/H···S (6.1%), and N···H/H···N (3.2%).</p> Graphical Abstract <p>Crystal Structures of Two Diorganotin Complexes Are presented, Including a New Diorganotin Sulfide [R₂Sn(µ-S)]₂ Exploiting O→Sn Intramolecular Coordination Arising from 2-acetamido-5-methylphenyl group.
