CRYSTAL STRUCTURE OF TRIPHENYLTIN (IV) FORMATE POLYMER, (HCO2SnPh3)n

Abstract

The title polymer [HCO2Sn(C6H5)3]n was isolated by serendipitous from reaction in ethanol 96 % between bis-(monocyclohexyl ammonium) 2-carboxyethyl hydrogen phosphonate, {(CyNH3)2[CO2CH2CH2PO2(OH)]} and triphenyltin chloride, SnPh3Cl. The polymer crystallizes in the monoclinic space group P21/n with Z = 4, a = 14.7091 (18) Å, b = 15.4133 (19) Å, c = 14.7639 (18) Å, β = 94.242 (2)° and V = 3338.0 (7) Å3. The structure consists of an infinite chain propagating along the crystallographic a-axis direction with bidentate formate anions. The O2SnC3 core is organized into a trans-trigonal bipyramidal like-arrangement.

Ladder-like Organostannoxane: Synthesis and Crystal Structure of the Second Polymorph {[(C6H5)2Sn]2[(C6H5)2ClSn]2(μ3-O)2(μ2-OH)2}∙[DMF]2

“…Very few compounds closely related to bis-[chloro-(µ 2 -hydroxo)-(µ 3 -oxo)-tetraphenyl-ditin] ladder, comprising solvate molecules were otherwise investigated [29][30][31][32]. Since decades, the Dakar group has been involved in the investigation of new organotin(IV) based materials [33][34][35][36][37][38], and more recently, singularly in ladder-like organostannoxanes derived from carboxylic acid [10]. In our course of isolating and investigating new organotin(IV) hybrid materials, we report in this work the synthesis and crystal characterization of the second polymorph organostannoxane, (1).…”
