Abstract

Diorganotin(IV)-complexes of the N-nitroso-N-phenylhydroxylaminates (hereinafter cupf), Et2Sn(cupf)2 (1), Bu2Sn(cupf)2 (2), {[Bu2Sn(cupf)]2O}2 (3), t-Bu2Sn(cupf)2 (4) and Oc2Sn(cupf)2 (5, 6) were prepared and characterised by FT-IR and Mössbauer spectroscopic measurements. The binding modes of the ligand were identified by FT-IR spectroscopy, and it was found that the ligand is coordinated in chelating or bridging mode to the organotin(IV) center. The 119Sn Mössbauer and FT-IR studies support the formation of trans-Oh (1-6) structures. The X-ray diffraction analysis of 4 revealed that the tin centre is in a skew-trapezoidal geometry defined by four donors derived from the cupferronato ligands and two carbon atoms from the tin-bound tbutyl substituents. The 119Sn NMR investigations indicate that in solution 4 retains its hexacoordinated nature.
