Coordination of Na by O in Na1.58CuO2. (a) Refined modulation functions; (b) modulation functions from Na1.6CuO2. The bond distances between Na and O as a function of the incommensurate parameter t are shown. The full and dashed lines apply to the modulated and basic structures, respectively. The t values representing the coordinations of Na in commensurate Na1.6CuO2 are indicated by vertical bars at t = 0.1875, 0.4375, 0.6875 and 0.9375.
