Five isostructural lanthanide MOFs, [Ln(1κOO',2κO'',3κO''',4κO''''-μ4-L)(NO3)(DMF)2]n·n(DMF) {Ln = La3+ (1), Ce3+ (2), Nd3+ (3), Sm3+ (4) and Dy3+ (5); L 5-[2-{2,4,6-trioxotetrahydropyrimidin-5(2H)-ylidene}hydrazinyl]isophthalate; DMF N,N'-dimethyl formamide}, based on dicarboxyl-functionalized arylhydrazone of barbituric acid were synthesized under solvothermal conditions. They characterized by elemental analysis, FT-IR spectroscopy, thermogravimetric X-ray diffraction analyses. Crystal...
Two known iron(iii) complexes, [Fe(H2O)3(L1)]·xH2O (x = 4 (1), 5 (2)) and [Fe(H2O)3(L2)]·3H2O (3), bearing the basic forms of 5-chloro-3-(2-(4,4-dimethyl-2,6-dioxocyclohexylidene)hydrazinyl)-2-hydroxybenzenesulfonic acid (H3L1) 3-(2-(2,4-dioxopentan-3-ylidene)hydrazinyl)-2-hydroxy-5-nitrobenzenesulfonic (H3L2), were prepared used as homogeneous catalysts for cyanosilylation a variety aldehydes with trimethylsilyl cyanide leading to corresponding cyanohydrin ethers. High yield (up 98 %) was...
The asymmetric units of the compounds, C 8 H 5 BrCl 2 O (I), and 9 Br (II), contain two one crystallographically independent molecules, respectively.

The asymmetric unit of the title compound, C9H10N2S, contains two crystallographically independent, almost planar, mol-ecules. In crystal, inter-mole-cular N-H⋯S hydrogen bonds link mol-ecules into pseudocentrosymmetric dimers, enclosing R 2 2(8) ring motifs. There are mutual π-π inter-actions between five- and six-membered rings each independent mol-ecule in chosen unit, with centroid-to-centroid distances 3.6685 (12) 3.7062 Å. A weak C-H⋯π(ring) inter-action is also observed. bonds,...

Reaction of α,α-dihalo-β-oxoaldehydes with diaminofurazan in acetonitrile affords unexpected 20-membered macrocycles.
Reaction of 2-chloro-2-(diethoxymethyl)-3-substitutedoxirane or 1-chloro-1-(substituted) -3,3-diethoxypropan-2-one with pyridine-2-thiol in EtOH at 25 °C yields 3-(diethoxymethyl)-3-hydroxy-2-substituted-2,3-dihydrothiazolo[3,2-a]pyridin-4-ium chlorides, which subsequently, MeCN 85°C, transforms into ring-opening products, 2-((2-carboxy-1-(substituted) -2-hydroxyethyl)thio)pyridin-1-ium chlorides. The tetrel (C···O) and chalcogen (S···O) bonds are found the structures 5 6, respectively....
