| 摘 要： | The crystal structures of biteplapalladite and biteplatinite have been determined using three-dimensional and two-diraeusional data respectively. Both of them has CdI2 structure type, with a space group of D3d^3, Z = 1, but the locatioa of (Te, Bi)deviates slightly from ideality. Atomic coordinates of the two minerals are identical:(Pd, Pt, Ni) or (Pt, Ni) is (001/2), (Te, Bi) is (1/3 2/3 0.242, 2/3 1/3 0.758). The R value of biteplapalladite is 0.075, and that of biteplatinite is 0.09. It can be regarded that all minerals in the system biteplatinite-merenskyite belong to the same structure type of CdI2.
