Abstract

A series of cis-bis{5-[(E)-2-(aryl)-1-diazenyl]quinolin-8-olato}dimethyltin(IV), Me2Sn(L)2, and chloro-{5-[(E)-2-(aryl)-1-diazenyl]quinolin-8-olato}dimethyltin(IV), Me2SnCl(L), complexes have been synthesized by reacting the sodium salts of 5-[(E)-2-(aryl)-1-diazenyl)quinolin-8-ol (LH) and dimethyltin dichloride in 2:1 and 1:1 molar ratios, respectively. These complexes have been characterized by 1H, 13C, 119Sn NMR in solution and by IR and 119Sn Mössbauer spectroscopy in the solid state. The structures of two of the dimethyltin(IV) complexes, viz., Me2Sn(L2)2 (2) and Me2SnCl(L3). C7H8 (6) (L2 = 5-[(E)-2-(4′-methoxyphenyl)-1-diazenyl)quinolin-8-olate, L3 = 5-[(E)-2-(4′ ethoxyphenyl)- 1-diazenyl)quinolin-8-olate), were determined by single crystal X-ray diffraction. In general, the Me2Sn(L)2 complexes were found to adopt a distorted cis-octahedral arrangement, while Me2SnCl(L) complexes have a distorted trigonal bipyramidal coordination geometry around the tin atom in solution and in the solid state.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
