The synthesis and characterization of selenium‐containing stannanes, ( o ‐MeSeC 6 H 4 CH 2 )Sn(Ph) 3– n Cl n [ n = 0 ( 1Se ); 1 ( 2Se ); 2 ( 3Se )], is presented. The increasing Lewis acidity at tin in the series 1Se → 2Se → 3Se is reflected in their respective solid state arrangements and supramolecular architecture by interactions of the type Se ··· Se, Sn ··· Se, and Cl ··· H–C. Overall the capacity of the selenium atom to form bidentate interactions creates geometric assemblies distinctly different to those of the oxygen and sulfur analogs.
