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.
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.
[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].
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).
