- 中文摘要: The undecanuclear copper cluster Cu11(m9-Se)(m3-I)3[Se2P(OEt)2]6 1, has been isolated along with Cu8(m8-Se)[Se2P(OEt)2]6 2, from the reaction of NH4Se2P(OEt)2, Cu(CH3CN)4PF6, and Bu4NI in a molar ratio of 3:2:2 in diethyl ether. The molecular formulation of 1 was confirmed by elemental analysis, positive FAB mass spectrometry, multinuclear NMR (1H, 31P, and 77Se), and X-ray diffraction. In cluster 1 eleven copper atoms adopt the geometry of a 3,3,4,4,4-pentacapped trigonal prism with a selenium atom in the center. The coordination geometry for the central, nonacoordinated selenium atom is tricapped trigonal prismatic. In addition, the central core Cu11Se is further stabilized by three iodides and six dsep ligands. Besides, weak inter-molecular Se···I interactions (3.949-3.972 A) are uncovered and form a one dimensional polymeric chain.
