Avoiding negative charge: Combined experimental and theoretical evidence shows that neutral, nine-atom tin-bismuth clusters adopt structures of closely related tin (poly)anions (see figure; Sn gray, Bi blue). These clusters exhibit similar bonding arrangements as known from Zintl ions. Hence, element substitution can be used to eliminate the negative charge without affecting the bonding or structural motif.
