摘要：
The reduction of 4,6-di-tert-butyl-N-(2,6-di-iso-propylphenyl)-o-iminobenzoquinone (imQ) by tin amalgam in hexane solution leads to new six-coordinated o-iminoquinonato tin(IV) complex (iSQ)(2)SnAP (1) (where iSQ and AP are o-iminosemiquinolate and dianion o-amidophenolate, respectively). Variable temperature magnetic susceptibility measurements of I have shown that this complex possesses a weak ferromagnetic exchange between o-iminosemiquinonate ligands. The oxidation of 1 with air oxygen produces new o-iminoquinonolate tin(IV) derivatives[(iSQ)Sn(AP)](2)O (2) and (iSQ)(2)Sn(OH)(2) (3) containing mu-oxo- and hydroxo-ligands, respectively. The electronic structure of 1 was examined by DFT analysis. Complexes 1-3 have been investigated using single-crystal X-ray diffraction. (C) 2009 Wiley Periodicals, Inc.
