Pyridinium bis(pyridine-κN)tetrakis(thiocyanato-κN)ferrate(III)–pyrazine-2-carbonitrile–pyridine (1/4/1)
In the title compound, (C5H6N)[Fe(NCS)4(C5H5N)2]·4C5H3N3·C5H5N, the Fe(III) ion is located on an inversion centre and is six-coordinated by four N atoms of the thio-cyanate ligands and two pyridine N atoms in a trans arrangement, forming a slightly distorted octa-hedral geometry. A half-occupied H atom attached to a pyridinium cation forms an N-H⋯N hydrogen bond with a centrosymmetrically-relat...
متن کاملAdsorption Behavior of MWAR Toward Gd(III) in Aqueous Solution
Adsorption and desorption behavior of Gd(III) ionon macroporous weak acid resin (MWAR) had been investigated.The influence of operational conditions such as contact time, initial concentration of Gd(III) ion, initial pH of solution and temperature on the adsorption of Gd(III) ion had been examined. Experimental data were exploited for kinetic and thermodynamic evaluations ...
متن کاملStability of colistimethate sodium in aqueous solution.
Colistimethate sodium, increasingly used to treat multidrug-resistant Gram-negative infections, spontaneously hydrolyzes to form colistin A (polymyxin E1) and B (polymyxin E2/B) when mixed with water. High levels of these active breakdown products at the time of administration have been associated with nephrotoxicity and even death. In this study, reconstituted colistimethate sodium was shown t...
متن کاملReaction between 3-hydroxy pyridine alkyl isocyanides and dialkyl acetylenedicarboxylate: synthesis of 4H-chromenes
The reactive intermediate generated by the addition of tert-butyl and 1,1,3,3-tetramethyl butyl isocyanide and cyclohexyl isocyanide to dialkyl acetylenedicarboxylate was trapped by 3-hydroxy pyridine to produce highly functionalized 4H-chromenes in fairly good yields.
