General Description

Trisodium arsenide, a chemical compound with the formula Na3As, is a highly toxic and reactive substance. It is composed of three sodium ions and one arsenic ion, and is typically produced through the reaction of sodium with arsenic. Trisodium arsenide is a strong reducing agent, meaning it can donate electrons to other substances in chemical reactions. trisodium arsenide is not commonly used in industrial or commercial applications due to its extreme toxicity and health hazards. Exposure to trisodium arsenide can result in severe poisoning and even death, making it a highly dangerous and unregulated compound.

The 2-Arsaethynolate Anion: Synthesis and Reactivity Towards Heteroallenes

The synthesis and isolation of the 2-arsaethynolate anion, AsCO?, and its subsequent reactivity towards heteroallenes is reported. Reactions with ketenes and carbodiimides afford four-membered anionic heterocycles in formal [2+2] cycloaddition reactions. By contrast, reaction with an isocyanate yielded a 1,4,2-diazaarsolidine-3,5-dionide anion and the unprecedented cluster anions As102?and As124?. These preliminary reactivity studies hint at the enormous potential synthetic utility of this novel anion, which may be employed as an arsenide (As?) source.

Flux requirements for the growth of RFeAsO (R=rare earth) superconductors

Millimeter-sized LaFeAsO single crystals have been successfully grown out of NaAs flux starting with (LaAs+1/2 Fe2 O3):20NaAs. The factors which allow the growth of these crystals out of NaAs but not out of many other fluxes, such as FeAs, have been investigated. X-ray powder diffraction found that NaAs synthesized for the growth of RFeAsO superconductors has monoclinic LiAs structure. Thermal analysis confirmed that NaAs melts congruently at about 600 °C. The ability to extract RFeAsO crystals from this NaAs flux suggests that NaAs has a significant oxygen solubility, possibly due to the formation of the ternary compound NaAsO2, and enough oxygen diffusivity to transport solute to the growth front. Oxygen solubility and diffusivity are two important factors in searching for an alternative environmentally benign flux for the growth of RFeAsO superconductors.
