摘      要：To investigate the reactivity of homoatomic clusters[E_(9)]^(4-)(E=Si-Pb)and intermetalloid clusters[M@E_(9)]^(q-),the reactions of the Zintl anions[Sn_(9)]^(4-) and[Ni@Sn_(9)]^(4-) with the CdMes_(2)(Mes=Mesitylene)in the presence of 2.2.2-crypt were carried *** new compounds[K(2.2.2-crypt)]_(6)[(Sn_(9))Cd(Sn_(9))]·en(1)and[K(2.2.2-crypt)]_(6)[(Ni@Sn_(9))Cd(Ni@Sn_(9))]·en(2)were *** 1 and 2 were characterized by single-crystal X-ray diffraction,energy dispersive X-ray(EDX),and electrospray ionization mass spectrometry(ESI-MS),and can be viewed as two[Sn_(9)]^(4-)or[Ni@Sn_(9)]^(4-)subunits bridged by Cd ion in an η^(3):η^(3) coordination *** chemical calculations reveal the relationships between the geometries and electronic structures of clusters 2a,[Ni_(3)Ge_(18)]^(4-)and[Cu_(4)@Sn_(18)]^(4-).Further electron localization technique(Ad NDP method)was performed to explain chemical bonding patterns of 1a.
