Silver nanoclusters containing Ag0 atoms protected by amino acids were synthesized and characterized. Chiral superatomic silver nanoclusters [Ag47 L12 (C≡Ct Bu)16 ]BF4 (L=l-/d-valine or l-/d-isoleucine) have been prepared by reducing AgC≡Ct Bu and amino acids (AAs) with NaBH4 . Single crystal X-ray diffraction revealed that these clusters have T symmetry, and the Ag47 metal kernel can be viewed as a tetracapped truncated tetrahedron (Ag17 ) surrounded with six W-shaped Ag5 units. The clusters are homochiral as evidenced by CD measurements
