From: Ternary aromatic and anti-aromatic clusters derived from the hypho species [Sn2Sb5]3−
a [Mo2(CO)6Sn2Sb5]3−, b [(CuSn2Sb5)2]4−. ON denotes occupation numbers (equal to 2.00 |e| in an ideal case). Lines between atoms are presented for visualization and do not necessarily correspond to 2c–2e bonds. Sn-atoms are dark yellow, Sb-atoms are blue, Mo-atoms are green, C-atoms are gray, Cu-atoms are dark red and O-atoms are red.
