The title compound, [Sn(C₆H₅)Cl₃(C₁₂H₈N₂)], which was obtained by the reaction between 1,10-phenanthroline and phenyl-tin trichloride in methanol, exhibits intra-molecular hydrogen-bonding inter-actions involving the chlorine and hydrogen atoms. Crystal cohesion is ensured by inter-molecular C-H?Cl hydrogen bonds, as well as Y-X?p and p-stacking inter-actions involving three different aromatic rings with centroid-centroid distances of 3.6605 (13), 3.9327 (14) and 3.6938 (12) Å]. Hirshfeld surface analysis and the associated two-dimensional fingerprint plots reveal significant contributions from H?H (30.7%), Cl?H/H?Cl (32.4%), and C?H/H?C (24.0%) contacts to the crystal packing while the C?C (6.2%), C?Cl/Cl?C (4.1%), and N?H/H?N (1.7%) inter-actions make smaller contributions.
