  Synthesis and characterisation of tin(IV) fluoride complexes of phosphine and arsine oxide ligands

  摘要：

  The pseudooctahedral complexes [SnF4L2] (L = Ph3PO, Ph3AsO, Me3PO, Me3AsO) and [SnF4(L-L)] (L-L = Ph2P(O)CH2P(O)Ph-2, o-C6H4(P(O)Me-2)(2), o-C6H4(P(O)Ph-2)(2)) have been prepared from [SnF4(MeCN)(2)] and the appropriate ligand in dichloromethane solution. The complexes have been characterised by analysis, IR, H-1, P-31{H-1}, F-19{H-1} and Sn-119 NMR spectroscopy as appropriate; the NMR studies showing that the complexes of the monodentate ligands exist as mixtures of trans and cis isomers in solution. The crystal structures of trans-[SnF4(OPMe3)(2)], [SnF4{o-C6H4(P(O)Ph-2)(2)}] center dot CH2Cl2 center dot H2O and [o-C6H4(P(O)Ph-2)(2)] center dot CH2Cl2 have been determined. Comparison of the structural and NMR spectroscopic data of the tetrafluorotin complexes with those of related [SnX4L2] (X = Cl, Br or 1) shows that SnF4 is the strongest Lewis acid in the series towards hard Lewis bases.

  Reactions of tetraethylammonium pentachlorostannate(IV) with a variety of Lewis bases have been investigated. Those with acetonitrile, pyridine, tetrahydrofuran, and salicylaldehyde as base (L) result in the formation of adducts [NEt4][SnCl5·L], while with trimethylamine, 2,2′-bipyridyl (bipy), phosphines, arsines, phosphine oxides, and arsine oxides the products are [NEt4]2[SnCl6] and 1:2 adducts

  已经研究了五氯锡酸四乙铵（IV）与多种路易斯碱的反应。以乙腈，吡啶，四氢呋喃和水杨醛为碱（L）的那些会导致形成加合物[NEt 4 ] [SnCl 5 ·L]，而与三甲胺，2,2'-联吡啶（bipy），膦、,、氧化膦和氧化砷的产物是[NEt 4 ] 2 [SnCl 6 ]和四氯化锡（IV）的1：2加合物（在联吡啶的情况下为1：1加合物）。与喹啉-8-醇（Hquin），戊烷-2,4-二酮（Hpd）和对pol酮（Htrop）的反应导致HCl的消除和[NEt 4 4] [SnCl 4的形成L']（L'= quin，pd或trop）。加合物[NEt 4 ] [SnCl 5 ·L]的Mössbauer四极分裂数据与从点电荷模型预测的数据一致。
