crystal data
Single crystals of Pb3Bi2[□|(GeO4)3], a new apatite-like compound with space group P63/m or P63, were grown from the melt. The unit-cell parameters are a = 10.034 (1) and c = 7.267 (2) Å, Z = 2, Dm = 7.51 and Dx = 7.60 g cm−3. Indexed powder data are given. The possibility of a ferroic phase transformation is discussed.
