Figure 2

The experimental diffraction pattern of (A) BF (red) and (B) BFCN (blue), denoted by circle. The solid line (black) represents the calculated diffraction pattern. The difference between the curves denoted in pink colour and the vertical tick (green) indicates the Bragg’s position. The diffraction pattern of pure CN is shown in the inset (B). (C) Structural representation of BFCN. The unit cell representation of CN (inset: I, II) and BF (inset: III).
