The crystal structure of Li{sub 3.4}Ga{sub 0.2}SiO{sub 4} has been determined by Rietveld refinement of time-of-flight neutron HRPD data. A total of 67 position, thermal, occupancy, and instrument parameters were refined to a final R{sub wp} = 5.24%, R{sub ex} = 4.20%. The structure is related to that of monoclinic, disordered Li{sub 4}SiO{sub 4}. It contains isolated SiO{sub 4} tetrahedra, six sets of partially occupied sites for lithium, and gallium with partial occupancy on one of the tetrahedral lithium sites. The similarities between this structure and those of rutile and {beta}-BeO are discussed.
