Molecular nanocluster with a [Sn(4)Ga(4)Zn(2)Se(20)](8-) t3 supertetrahedral core.
A multinary molecular nanocluster, in which a T3 supertetrahedral [Sn(4)Ga(4)Zn(2)Se(20)](8-) core was neutralized and covalently terminated by four [(TEPA)Mn](2+) (TEPA = tetraethylenepentamine) metal complexes, was synthesized and characterized. The cluster is assembled into, through hydrogen bonding and van de Waals forces, a superlattice that is chemically stable and free of strong covalent coupling. The four different cations were distributed within the cluster in such a manner that both the local charge balance and global charge compensation by the metal complex could be satisfied.
