The syntheses, structures, and magnetic properties of a series of tetranuclear cyanide-bridged compounds are reported. This family of molecular squares, [{M(II)Cl2}2{Co(II)(triphos)(CN)2}2] (M = Mn ([CoMn]), Fe ([CoFe]), Co ([CoCo]), Ni ([CoNi]), and Zn ([CoZn]), triphos = 1,1,1-tris(diphenylphosphinomethyl)ethane), has been synthesized by the reaction of Co(II)(triphos)(CN)2 and MCl2 (M = Mn, ...

The U.S. Environmental Protection Agency’s (USEPA) current ambient water quality criteria (AWQC) for cyanide were developed in 1984. Since this time, additional research on cyanide toxicity and analytical chemistry has suggested that cyanide AWQC values need to be updated to reflect the current state-of-the-science and to ensure that the methods for implementing the cyanide AWQC reflect the bio...

Acyl carrier proteins (ACPs) are central hubs in polyketide and fatty acid biosynthetic pathways, but the fast motions of the ACP's phosphopantetheine (Ppant) arm make its conformational dynamics difficult to capture using traditional spectroscopic approaches. Here we report that converting the terminal thiol of Escherichia coli ACP's Ppant arm into a thiocyanate activates this site to form a s...

The caption for Figure 5 in the original publication incorrectly stated that data for complexes 1−4 were shown. It should refer only to data for complex 1. The corrected caption reads as follows: Figure 5. Bar graph showing the mitochondrial membrane polarization, determined by a reduction in red (FL2) fluorescence, by complex 1 against that of a negative and positive control (5 μM carbonyl cya...

cyanide ion, is an environmentally significant pollutant in many industrial wastewaters.therefore, a considerable number of methods have been studied for the wastewater treatment containingcyanide. the goal of our work consists in applying a simple and economic process for solving this problem ofpollution. the removal of cyanide ions by using three anion exchange membranes has been studied unde...

abstract cyanide is a colorless, harmful, and dangerous substance with a smell similar to bitter almond. cyanide forms a stable compound with iron and magnesium and interferes with cell activity by interfering with respiration, carbon stabilization and nitrate revival. in order to evaluate cyanide metabolism in fuji and abassi mashhad apples, a factorial experiment was conducted as split plot b...

Capillary zone electrophoresis with on-column UV detection at 214 nm was used to detect and determine iron cyanide complexes in liquid samples from zinc electroplating processes. Using a cathodic injection and anodic detection scheme, hexacyanoferrate(T1) and -(III) ions were separated with baseline resolution in under 5 min. A linear relationship between peak area and concentration was obtaine...

Diimidazolium salts featuring different bridges between the imidazolium groups, as well as electron-withdrawing groups (chloride, cyanide) at the 4- and 5-position of the heterocyclic rings, have been successfully prepared. The diimidazolium salts serve as convenient precursors of di(N-heterocyclic carbene) ligands, which coordinate in a chelating fashion to palladium(ii) centres. The effect of...
