520	3		_aThe crystal structure of Ca3Co4O9 was investigated using high-resolution transmission electron microscopy (HRTEM)and the image-simulation method. The c* was 10.8Å and the b parameters were 4.56Å for the Ca2CoO3 block and 2.82Å for the CoO2 sheet. The [110]zone axis HRTEM images confirmed that Ca3Co4O9 has a modulated layered structure with modulation. For the first time, the atomic positions of the Ca and Co atoms in the Ca2CoO3 block were identified, corresponding to three rows of dark spots in the [110]direction. The observed HRTEM images for Ca2CoO3 agreed well with the calculated images based on the structural model obtained by the Rietveld refinement method.
