    • The average Zn-Zn distance and the Sn-Sn distance in the {Zn 8So4} cluster are d(Zn-Zn)∅, 2.759 Å and d(Sn-Sn, 3.038(1) Å. For comparison, the interatomic distance in elemental zinc is d(Zn-Zn, 2.665 Å, and the average interatomic distance in the (Sn14) substructure is d(Sn-Sn)∅, 2.909 Å. The intracluster Zn-Sn distances are d(Zn-Sn, 2.729(2)-2.856(1) Å, and the corresponding exo-cluster contacts are d(Zn-Sn, 2.724(1)-2.914(1) Å. b) Mo7Sn12Zn40[14a] contains molybdenum-centered icosahedra of composition {MoZn10Sn2} with Zn-Sn distances similar to those in Na29Zn24Sn 32
