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.
