The article presents structural features at formation of solid solutions of the isostructural Mg2P2O7 and Mg2As2O7 connections. In these compounds, complex Р2О7 4- anions, As2O2 4- , as well as the formation of complex PAsO7 4 anions, is not natural. The formation of solid solutions is confirmed by the linear dependence of x-ray debaegram and optical refractive indices, depending on the concentration of P/As. In the article, phosphates are involved in energy processes in cells. For the first time, the formation of mixed anions in polyphosphates has been proven. The oscillatory spectra of pyro

Resumen
The reaction of (isocyanide)gold(I) chlorides [(RNC)AuCl, R = tBu, cHex] with phenylene- 1,2-dithiol and sodium methoxide (molar ratio 2:1:2) in methanol / dichloromethane leads to the formation of deep green mixed-valent salts [(RNC)2Au]+[Au(S2C6H4)2]- in ca. 35% yield. As determined by single crystal X-ray diffraction methods, the two compounds have entirely different supramolecular structures. For R = tBu stacked planar anions and rod-like cations form alternating layers, while for R = cHex alternating cations and anions are arranged in chains with long S- -Au contacts [3.422 Å].

The results show the [Me2HNCH2]2 2+ dication to be a highly flexible template for halide inclusion, thereby tolerating the assembly of anions of different size, with phase widths of 0 ≤ x ≤ 2 for a monoclinic form with [Me2HNCH2]2I2−xBrx and 0 ≤ x ≤ 1 for a triclinic form with [Me2HNCH2]2Br2−xClx.

Resumen
In this chapter we discuss the structures, properties and applications of mixed anion materials—solid state compounds that contain at least two different anions directly co-ordinated to metal ions, which are also known as heteroanionic materials. We focus on the most common types found in the literature, materials containing two different anions of which one is oxide, and divide these into two classes dependant on the nature of the second anion. In the first type the oxide anion is paired with an isoelectronic ‘light’ anion such as oxide or fluoride. We use the widely investigated oxynitrides

Resumen
Abstract Enolate anions are one of the most widely used nucleophilic species in organic synthesis. Organocopper conjugate addition to α,β-unsaturated carbonyl compounds generates in situ metal enolates under mild conditions with the incorporation of an organic group to the β-position. Therefore, the organocopper-mediated reaction followed by the regioselective enolate trapping provides an extremely powerful tool for controlled construction of organic frameworks (see Scheme 9.1). The organocopper reagents commonly used for this tandem reaction can be divided into four general classes: (1) Grign
