New alkaline earth-gold-aluminides were synthesized from the elements in sealed tantalum or quartz ampoules in muffle furnaces at maximum annealing temperatures of 1325 K. The structures were refined from single crystal X-ray diffractometer data. SrAu 3 Al 2  crystallizes in an ordered version of the LT-SrZn 5  structure:  Pnma ,  a  = 1315.9(3),  b  = 549.0(1),  c  = 684.5(3) pm,  wR 2 = 0.0232, 930  F  2  values, 35 variables. SrAu 2.83 Al 2.17  ( a  = 1065.0(2),  b  = 845.0(2),  c  = 548.1(1) pm,  wR 2 = 0.0416, 452  F  2  values, 22 variables) and BaAu 2.89 Al 2.11  ( a  = 1096.1(3),  b  = 835.7(3),  c  = 554.0(1) pm,  wR 2 = 0.0280, 501  F  2  values, 22 variables) both adopt the BaZn 5  type, space group  Cmcm  with Au/Al mixing on the 4 c  site. The gold and aluminum atoms in both types form three-dimensional networks of condensed tetrahedra with the strontium and barium atoms in large cavities. BaAu 7.09 Al 5.91  is a new member of the NaZn 13  type:  Fm 3̅ c ,  a  = 1257.6(2) pm,  wR 2 = 0.0267, 168  F  2  values, 12 variables. Both the 96 i  and 8 b  sites show Au/Al mixing. The crystal chemical details are discussed.
