Main Group Metal Directed Self-Assembly in a Tetrameric Trimethyltin(IV)N-nitroso-N-phenylhydroxylaminato Complex Containing an Unprecedented 20-Membered Inorganic (Carbon-Free) Metallamacrocycle

Abstract

Tetrakis[trimethyl(N‐nitroso‐N‐phenylhydroxylaminato)tin(IV)] was synthesized by reaction of cupferron ([PhN(O)NO]NH4) with trimethyltin(IV) chloride. The complex was characterized by X‐ray diffraction analysis, FT‐IR and FT‐Raman spectroscopy. An X‐ray structural analysis of the title complex [Me3Sn(O2N2Ph)]4 reveals the first example of a bridging coordinated cupferronato ligand. This coordination pattern leads to an unprecedented inorganic 20‐membered (carbon‐free) metallamacrocycle Sn4O8N8 in which four Me3Sn and four PhN2O2 subunits are self‐assembled.
