Single crystals of Pb 3 Bi 2 [□|(GeO 4 ) 3 ], a new apatite‐like compound with space group P 6 3 / m or P 6 3 , were grown from the melt. The unit‐cell parameters are a = 10.034 (1) and c = 7.267 (2) Å, Z = 2, D m = 7.51 and D x = 7.60 g cm −3 . Indexed powder data are given. The possibility of a ferroic phase transformation is discussed.
