Abstract
The NdCl3–Li6P6O18–H2O system is studied at 20°C, NdCl3 concentrations of 0.05 to 0.1 mol/l, and Li6P6O18 concentrations of 0.025 to 0.15 mol/l. Simple cyclohexaphosphates with the general formula Nd2P6O18 · mH2O (m = 6, 8, 12) are identified, and the double cyclohexaphosphate Li3Nd3(P6O18)2 · 26H2O is obtained for the first time. Li3Nd3(P6O18)2 · 26H2O has a monoclinic structure with unit-cell parameters a = 24.24 Å, b= 9.24 Å, c = 14.53 Å, and β = 125.24°.
