Abstract
Precise X-ray powder diffraction data are given for two germanides, CoGe and Co5Ge7. The refined unit cell parameters for CoGe are a= 11.630(1) A, b=3.8014(3) A, c=4.9347(3) A and (3 = 100.889(8)° (space group C2/m, Pearson symbol mC16) with volume of the unit cell 214.24(2) A^3 the figures of merit are M20=96, F3o=77 (0.0085, 46). The refined unit cell parameters for Co5Ge7 are a = 7.6262(4) A and c= 5.8017(5) A (I4mm, tI24) with volume of the unit cell 337.42(3) A^3 the figures of merit are M2o=204 and F^= 130(0.0068,25). The dependence on composition of the unit cell parameters of CoGe is discussed in terms of specific defect structures.
