Correlations between 9Be magic-angle spinning nuclear magnetic resonance spectra and the geometry of beryllium

Abstract:
A range of sodalite framework structures containing beryllium with general formula M8[BeZO4]6X2; M = Cd, Zn, Z = Si, Ge and X = S, Se or Te have been synthesised. The structures of these materials, which contain a single beryllium environment, have been refined from powder neutron diffraction or powder X-ray diffraction data and the compounds further characterised using 9Be magic-angle spinning nuclear magnetic resonance (MASNMR). Spectra show a single sharp resonance for 9Be(OSi)4 in the chemical shift range +/- 1 ppm from 0.1 M BeCl2. Correlations between the Be-O-Z bond angles and the 9Be chemical shift are reported and show upfield shifts for larger angles as seen previously in MASNMR spectra for 29Si and 27Al.

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
