New complex phosphates Cs3MIIBi(P2O7)2 (MII - Ca, Sr and Pb): synthesis, characterization, crystal and electronic structure.

Herein, the peculiarities of complex phosphate formation in self-fluxes of Cs-MII-Bi-P-O (MII = Ca, Sr, Ba and Pb) systems with Cs/P = 0.7-1.3 at fixed ratios of Bi/P = 0.2 and Bi/MII = 1.0 were studied and discussed. Three novel isostructural diphosphates with the general composition Cs3MIIBi(P2O7)2 (MII = Ca, Sr and Pb) and the original framework topology… CONTINUE READING
