The ternary intermetallic compounds CaBe2Ge2, BaMg2Pb2 and BaZn2Sn2 have been prepared. Their crystal-structures have been determined. They are isotypic and crystallize in a new variant of the BaAl4-type (Space group: P4/nmm — D4h7, lattice parameters: CaBe2Ge2: a = 4,02 ± 0,02 Å c = 9,92 ± 0,02 Å BaMg2Pb2: a = 5,00 ± 0,02 Å c = 12,11 ± 0,02 Å BaZn2Sn2: a = 4,69 ± 0,02 Å c = 11,33 ± 0,02 Å).
