Bis[N,N-bis­(2-hydroxy­ethyl)dithio­carbamato-κ2 S,S′]copper(II)

In the title compound, [Cu(C5H10NO2S2)2], the CuII cation is chelated by two bis­(2-hydroxy­ethyl)dithio­carbamate anions with a distorted square-planar coordination geometry. Inter­molecular O—H⋯O hydrogen bonding is observed between the terminal hydr­oxy groups in the crystal structure

Methyl 4-methyl­sulfonyl-2-nitro­benzoate

The title compound, C9H9NO6S, was prepared by the reaction of methanol and thionyl chloride with 4-methyl­sulfonyl-2-nitro­benzoic acid under mild conditions. The dihedral angle between the nitro group and benzene ring is 21.33 (19)° and that between the carboxyl­ate group and the benzene ring is 72.09 (17)°. The crystal structure is stabilized by weak inter­molecular bifurcated C—H⋯O inter­actions occurring in the (100) plane

Ethyl N-[3-(N,N-dimethyl­carbamo­yl)pyridin-2-ylsulfon­yl]carbamate

In the mol­ecular structure of the title compound, C11H15N3O5S, the amide group is nearly perpendicular to the pyridine ring, making a dihedral angle of 86.30 (13)°. The terminal ethyl group is disordered over two sites of equal occupancy. Inter­molecular N—H⋯O hydrogen bonding is present in the crystal structure

Bis(2-benzyl­imino­methyl-4,6-dihydro­seleno­phenolato)iron(II)

In the title compound, [Fe(C14H12NOSe2)2], the FeII ion (site symmetry ) is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a slightly distorted trans-FeN2O2 square-planar coordination for the metal ion
