Triclinic LaZnP with P, P, and P units: a combined study by P solid-state NMR spectroscopy and single crystal X-ray diffraction.

The ternary polyphosphide LaZnP was synthesized from the elements by using a salt flux or a ceramic method in sealed quartz ampoules. The obtained samples were investigated by X-ray powder and single crystal diffraction: own type, 1̄, = 775.33(13), = 827.

Structural Role of Phosphate in Metaluminous Sodium Aluminosilicate Glasses As Studied by Solid State NMR Spectroscopy.

In this contribution we present a detailed study of the effect of the addition of small to intermediate amounts of PO (up to 7.5 mol %) on the network organization of metaluminous sodium aluminosilicate glasses employing a range of advanced solid state NMR methodologies. The combined results from MAS, MQMAS (multiple quantum MAS), or MAT (magic angle turning) NMR spectroscopy and a variety of dipolar based NMR experiments-Al{P}-, Al{Si}-, Si{P}-, and P{Si}-REDOR (rotational echo double resonance) NMR spectroscopy as well as P{Al}- and Si{Al}-REAPDOR (rotational echo adiabatic passage double resonance) NMR-allow for a detailed analysis of the network organization adopted by these glasses.
