In the title compound, [Co(C(4)H(7)N(2)O(2))Cl(2)(C(4)H(8)N(2)O(2))], the Co(III) ion has a distorted octa-hedral coordination environment. The equatorial plane consists of four N atoms, two each from the dimethyl-glyoxime and dimethyl-glyoximate ligands, while the two axial positions are occupied by two chloride ions. Strong intra-molecular O-H⋯O hydrogen bonds are observed between the dimethy...

The title salt, (C(12)H(12)N(4)O(2))[ReCl(6)], consists of 2,2'-[(1E,2E)-1,2-bis-(hy-droxy-imino)-ethane-1,2-di-yl]dipyridinium cations and [ReCl(6)](2-) anions which are both located on inversion centres. Each cation consists of a glyoxime moiety attached to two protonated pyridine rings in ortho positions. In the crystal, E,E isomers of the cation are observed which differ in the spatial arra...

Abstract Dioximes as ligands are used analytical reagents and serve models for biological systems well catalysts in chemical processes. A number of novel mixed complexes the type [Fe(DioxH) 2 (amine) ] have been prepared characterised by FTIR, 57 Fe Mössbauer mass spectroscopy us. We found strong Fe–N donor acceptor interactions iron occurred low-spin II state all complexes. Later, we also that...

In the title compound, C(10)H(8)N(2)·C(4)H(8)N(2)O(2), both the dimethyl-glyoxime and the 4,4'-bipyridine mol-ecules have crystallographic C(i) symmetry. The mol-ecules stack along the a-axis direction with a dihedral angle of 20.4 (8)° between their planes. In the crystal, the components are linked by O-H⋯N hydrogen bonds into alternating chains along [120] and [1[Formula: see text]0].

A new poly(vinylchloride) membrane sensor for Cr3+ ions based on di (benzylamino)glyoxime asan ionophore was prepared. The electrode has a linear dynamic range 1×10-6-1×10-1 mol l-1,with aNernstian slope of 20.3 ± 0.5 mV per decade and a detection limit of 2×10-7. It has a fast responsetime of

We report the preparation of a dicobalt compound with two singly proton-bridged cobaloxime units linked by a central [BO4] bridge. Reaction of a doubly proton-bridged cobaloxime complex with trimethyl borate afforded the compound in good yield. Single-crystal X-ray diffraction studies confirmed the bridging nature of the [BO4] moiety. Using electrochemical methods, the dicobalt complex was foun...

n, n΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of n, n΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚c. under similar conditions n, n΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and n, n΄-3, 4-di(isopropylamino)-1, 2, 5-oxadiazole (1e) were not obtained, but, n, n΄-3, 4-di(ethylamino)-1, 2, 5-oxadiazole (1g) was appeared with smal...
