Single-crystal X-ray analysis has verified preparation of an ideal magnetoplumbite-type phase in the ternary barium hexagallate system. X-ray refinement was carried out by the full-matrix least-squares on F{sup 2} method, to give R{sub 1} = 4.61% and wR{sub 2} = 7.76% for 54 parameters and 374 independent reflections with I > 2{sigma}(I). Microanalysis data yields a composition of Ba{sub 1.07}Ga{sub 11.95}O{sub 19}. The crystal chemistries of the barium hexagallate and barium hexaaluminate systems are compared and discussed. Crystal data for BaGa{sub 12}O{sub 19}: M = 1277.98, space group P6{sub 3}/mmc (No. 194), a = 5.8140(8) {angstrom}, c = 23.038(5) {angstrom}, V = 674.4(2) {angstrom}{sup 3}, Z = 2, D{sub c} = 6.293 g cm{sup {minus}3}, MoK{alpha}, {lambda} = 0.71073 {angstrom}, {mu} = 26.532 mm{sup {minus}1}, 2{theta}{sub max} = 56.74{degree}.
