Tris(cyclohexylammonium)cis-dichloridobis(oxalato-κ²O¹,O²)stannate(IV) chloride monohydrate

Abstract

The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo­hexyl­ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol­ecule. The cyclo­hexyl­ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa­hedrally to the central SnIV atom. The cohesion of the mol­ecular entities is ensured by the formation of N—H⋯O, O—H⋯O, O—H⋯Cl and N—H⋯Cl inter­actions involving cations, anions and the lattice water mol­ecule, giving rise to a layer-like arrangement parallel to (010).

Synthesis, structure determination and characterization by UV–Vis and IR spectroscopy of bis(diisopropylammonium) cis-dichloridobis(oxalato-κ2 O 1,O 2)stannate(IV)

“…The C-O bond lengths of coordinating O atoms [O1-C7 = 1.289 (2) Å ; O4-C8 = 1.289 (2) Å ] are significantly longer than those of non-coordinating O atoms [O2-C7 = 1.222 (2) Å , O3-C8 = 1.223 (2) Å ]. The Sn1-C1l distance of 2.3422 (9) Å as well as the Sn-O distances of 2.0710 (16) Å (O1) and of 2.1057 (15) Å (O4) are slightly shorter than corresponding bonds reported previously (Reichelt & Reuter, 2014;Sarr et al, 2013;Diop et al, 2011;Sow et al, 2013;Skapski et al, 1974).…”

“…One of the motivations to study these compounds is related to the rich coordinating behaviour of the oxalato ligand, which can adopt a monodentate, a bridging monodentate, a bridging bidentate, a monochelating, bidentate or a bichelating mode (Miskelly et al, 1983;Sow et al, 2012;Ś witlicka-Olszewska et al, 2014). In this context, our group has previously published the syntheses and crystal structure determinations of some tin(IV) oxalate derivatives (Sarr et al, 2013(Sarr et al, , 2018. As a continuation of this work, we have studied the interaction between bis(diisopropylammonium) oxalate with tin(IV) chloride dihydrate, which yielded the title salt…”

“…A search in the Cambridge Structural Database (CSD, version 5.40, update Nov. 2018;Groom et al, 2016) resulted in 226 hits dealing with diisopropylammonium cations while only one hit deals with the [Sn(C 2 O 4 ) 2 Cl 2 ] 2anion (Sarr et al, 2013).…”

New Pyridine-3-Sulfonato Tin (Iv), Antimony (Iii) and (V) Halo Adducts and Complexes: Synthesis and Infrared Study

“…Let us consider the main IR data (in cm -1 ) of the six studied adducts and complexes: While considering the tin compounds, an oxidation of tin occurs in situ during the synthesis process [7]. ʋas(SnCl4) appears in the IR spectrum of 3 as a very strong and sharp band (Eu type) indicating a transcoordination according to Groups Theory.…”
