A multinary molecular nanocluster, in which a T3 supertetrahedral Sn(4)Ga(4)Zn(2)Se(20) core was neutralized and covalently terminated by four (TEPA)Mn (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.
合成并表征了一种多元分子纳米团簇，其中一个T3超四面体Sn(4)Ga(4)Zn(2)Se(20)核被四个(TEPA)Mn（TEPA = 四乙烯五胺）金属配合物中和并共价封端。该团簇通过氢键和范德华力组装成一种化学稳定且无强共价耦合的超晶格。四种不同的阳离子以这样一种方式分布在团簇内，即金属配合物既能满足局部电荷平衡，又能实现整体电荷补偿。
