Fig. 4.16 Simulated powder patterns derived from the single crystals of 1ch obtained by pricking
(green line) and crystal contact (light green line), and 1ac obtained by pricking (black line). Powder
diffraction patterns of 1ac samples obtained by crystal contact (blue line) and sonication (light blue
line)
Furthermore, the HOMO is distributed to near the gold atoms. Therefore, the difference of aurophilic interactions in tetramer of 1ch and 1ac should influence in the
emission/excitation properties of both crystals.
