Crystal structures of diformatotri­methyl­tin di­aquadi-μ-hydroxido-tris­(tri­methyl­stannate) and di-μ-hydroxido-tris­(tri­methyl­tin) chloride monohydrate

The title compounds are partially condensed products of hydrolysed tri­methyl­tin chloride. In the two structures, short cationic tris­tannatoxanes (C9H29O2Sn3) are bridged by a diformatotri­methyl­tin anion or a chloride anion.

Accepted 21 September 2016

Di­methyl­ammonium 2,4,5-tri­carb­oxy­benzoate: an example of the deca­rbonylation of N,N-di­methyl­formamide in the presence of a metal and a benzene­polycarb­oxy­lic acid. Is zirconium(IV) the Tsotsi?

The paper reports the mol­ecular and crystal structure of the salt (CH3)2NH2+·C10H5O8, with the cation formed by the deca­rbonylation of DMF solvent.

Accepted 21 September 2016

[N-Benzyl-N-(2-phenyl­eth­yl)di­thio­carbamato-κ2S,S′]tri­phenyl­tin(IV) and [bis­(2-meth­oxy­eth­yl)di­thio­carbamato-κ2S,S′]tri­phenyl­tin(IV): crystal structures and Hirshfeld surface analysis

Heavily distorted trigonal–pyramidal coordination geometries, each based on a C3S2 donor set and with the loosely bound S atom approximately trans to one of the ipso-C atoms, are found in the title compounds (C6H5)3Sn[S2CN(Ben)CH2CH2Ph] and (C6H5)3Sn[S2CN(CH2CH2OMe)2].

Accepted 19 September 2016

Crystal structure of bis­(azido-κN)bis­(quinolin-8-amine-κ2N,N′)iron(II)

Exploring the role of azido anions led to the structure of this heteroleptic Fe complex with two azide ions and two quinolin-8-amine ligands.

Accepted 1 September 2016

Crystal structures of (5RS)-(Z)-4-[5-(furan-2-yl)-3-phenyl-4,5-di­hydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid and (5RS)-(Z)-4-[5-(furan-2-yl)-3-(thio­phen-2-yl)-4,5-di­hydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid

Stereochemical peculiarities of (5RS)-(Z)-4-[5-(furan-2-yl)-3-phenyl-4,5-di­hydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid and (5RS)-(Z)-4-[5-(furan-2-yl)-3-(thio­phen-2-yl)-4,5-di­hydro-1H-pyrazol-1-yl]-4-oxobut-2-enoic acid, studied by X-ray structural analysis, render impossible their transformation into 3b,6-ep­oxy­pyrazolo­[5,1-a]iso­indoles by a thermal intra­molecular Diels–Alder reaction of furan (the IMDAF reaction).
