✦ Synopsis

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 fullmatrix least-squares on F 2 method, to give R 1 ‫؍‬ 4.61% and wR 2 ‫؍‬ 7.76% for 54 parameters and 374 independent reflections with I'2 (I). Microanalysis data yields a composition of Ba 1.07 Ga 11.95 O 19 . The crystal chemistries of the barium hexagallate and barium hexaaluminate systems are compared and discussed. Crystal data for BaGa 12 O 19 :
