Crystal structure of La5Ti4GaO17

The crystal structure of La5Ti4GaO17 compound synthesized by heat-treatment of the co-precipitated hydroxy-oxalates has been determined by the X-ray powder diffraction. It was found that crystal structure of La5Ti4GaO17 belongs to the CaLa4Ti5O17-type structure (space group Pmnn, a = 0.3912(1) nm, b = 3.128(1) nm, c = 0.5523(1) nm, Z = 2). The final RW value is equal to 0.081 for 169 independent reflections.
