Supramolecular architecture in crystalline Bu2NH2(PhPO3H)2SnMe3

Abstract

The title compound Bu 2 NH 2 (PhPO 3 H) 2 SnMe 3 was synthesized and its structure determined by single crystal X-ray crystallography. The structure consists of two monodentate hydrogenophosphonates [PhPO 3 H] -bonded to SnMe 3 groups leading to SnC 3 O 2 moiety in a trans trigonal bipyramidal environment. [(PhPO 3 H) 2 SnMe 3 ] -dimerizes through hydrogen bonds. Dibutylammonium (Bu 2 NH 2 + ) cations are hydrogen bonded to the dimeric moieties through phosphonates to give a chain structure.

“…-Molecular structure of 1showing the trigonal bipyramidal polyhedron at tin atoms. Ellipsoids are drawn at 50% probability.The Sn-C distances are in the range of those found in tbp SnMe 3 moieties(Diop et al, 2013a(Diop et al, , 2012b(Diop et al, , 2011a. The Sn1-O4 bond of 2.416 (2) Å is longer, weaker than the Sn1-O1 one of 2.1313(19) Å: these values are in a typical range of Sn-O phosphonate (Diop et al, 2013a, 2012a, 2012b) and Sn-O water (Diop et al, 2015), respectively.…”

“…In some of these structures, the hydrogenphosphonate anion behaves as multidirectional synthons. Contributing to widen phosphonate family compounds, the Dakar group has already reported the spectroscopic (Infrared, Mössbauer and NMR) studies of some RPO 3 (SnPh 3 ) 2 (R = H or CH 3 ) (Diop et al, 1999), the crystal characterization of dibutylammonium bis(hydrogen methylphosphonato-κO)triphenylstannate(IV) (Diop et al, 2012a) as well as numerous phenylphosphonato triphenyltin(IV) crystalline structures which, through hydrogen bonding interactions, exhibit various structures that give rise to supramolecular diverse topologies (Diop et al, 2013a(Diop et al, , 2012b(Diop et al, , 2011a(Diop et al, , 2011b. To the best of our knowledge (CSD version 5.40), very few, only three tin(IV) methylphosphonate and five tin(IV) hydrogenphosphonate containing crystalline compoundsare known (Diop et al, 2012a;Ribot et al, 2001;Adair et al, 1998;Chandrasekharet al, 2003Chandrasekharet al, , 2005Mairychova et al, 2014 (Mairychova et al, 2014) or an hexameric cage structure in a double O-capped cluster with tri-O-coordinating ligands (Chandrasekharet al, 2003(Chandrasekharet al, , 2005.…”

X-ray crystal structures of [(Cy2NH2)]3[C6H3(CO2)3]·4H2O and [i-Bu2NH2][(Me3 SnO2C)2C6H3CO2]

“…With this aim, several supramolecular organotin compounds have been synthesized and characterized (Chandrasekhar et al, 2003;Kapoor et al, 2005;Herntrich and Merzweiler, 2006). In our laboratory, some of them containing SnMe 3 and SnPh 3 residues have been recently published (Diop et al, 2011(Diop et al, , 2012Sow et al, 2012a,b). In this context, we have recently published a supramolecular trimethyltin(IV) triscarboxylate [Cy (Ndoye et al, 2012).…”
