Nanostructured Mn y Ga ribbons with varying Mn concentrations including Mn 1.2 Ga, Mn 1.4 Ga, Mn 1.6 Ga, and Mn 1.9 Ga were prepared using arc-melting and melt-spinning followed by a heat treatment. Our experimental investigation of the nanostructured ribbons shows that the material with y ¼ 1.2, 1.4, and 1.6 prefers the tetragonal L1 0 structure and that with y ¼ 1.9 prefers the D0 22 structur...

The reaction of Mn(2)(CO)(7)(mu-S(2)) with [CpNi(CO)](2) yielded the paramagnetic new compound Cp(2)Ni(2)Mn(CO)(3)(mu(3)-S)(2) (1) and a new hexanuclear metal product Cp(2)Ni(2)Mn(4)(CO)(14)(mu(6)-S(2))(mu(3)-S)(2) (2). Structurally, compound 1 contains two triply bridging sulfido ligands on opposite sides of an open Ni(2)Mn triangular cluster. EPR and temperature-dependent magnetic susceptibil...

Manganese (Mn) using as raw material for melting process in ferrous foundry and it is considered as a hazardous neurotoxic substance. The furnace-men and melting department workers are potentially exposed to manganese particles or fume in the workplace which accumulates in their central nervous system and neurological disorder observed for exposed workers. The objective of the research was to i...

Using the stable metalloradical Mn(CO)3(CNArDipp2)2, we report the formation of manganese-main group complexes via the single-electron functionalization of main group halides. The reactions occur in a simple 1 : 1 stoichiometry, and demonstrate the utility of using stable open-shelled organometallics as precursors for metal-main group compounds. This has enabled the preparation of manganese com...

The crystal structure of di-μ(3)-chlorido-tetra-μ(2)-chlorido-dichloridoocta-(imidazole-κN)tetra-manganese(II) ethanol 1.234 solvate, [Mn(4)Cl(8)(C(3)H(4)N(2))(8)]·1.234C(2)H(5)O or [Mn(4)Cl(8)(Him)(8)]·1.234EtOH, where Him is imidazole (C(3)H(4)N(2)), is based upon two Mn(4)Cl(4) cubes which share one face, and which each lack one manganese vertex, giving a Mn(4)Cl(6) unit. This contains two d...

Nine new manganese(III) fluorophosphates have been synthesised hydrothermally in a fluoride-rich medium, through the use of MnF(3), HPF(6) and monovalent metal fluorides as reactants. Products have been structurally characterised using single crystal X-ray diffraction. Reaction in fluoride-rich conditions produces chain, layer and three dimensional framework structures containing new and unusua...

Manganese (Mn) is an essential nutrient required for normal tissue growth and function. Following exposures to high concentrations of inhaled Mn, there is preferential accumulation of Mn in certain brain regions such as the striatum and globus pallidus. The goal of this research was to complete a physiologically based pharmacokinetic (PBPK) model for Mn in rats and scale the model to describe M...
