| Abstract: | Abstract Several copper and silver clusters containing diselenophosphate ligands such as tetranuclear [Cu{Se2P(OR)2}]4, hexanuclear [Ag{Se2P(OR)2}]6, octanuclear [Cu8(μ8-Se)}Se2P(OR)2}6], [Ag8(μ8-Se)}Se2P(OR)2}6], [Cu8(μ8-X)}Se2P(OR)2}6](PF6), [Ag8(μ8-X)}Se2P(OR)2}6](PF6), decanuclear [Ag10(μ10-Se)}Se2P(OR)2}8], undecanuclear [Cu11(μ9-Se)(μ3-X)3}Se2P(OR)2}6], [Ag11(μ9-Se)(μ3-X)3}Se2P(OR)2}6], and dodecanuclear [Cu12(P2Se6)}Se2P(OR)2}8] have been isolated. All these clusters were well characterized in the solid-state and solution phase by elemental analysis, positive FAB mass spectrometry, multinuclear NMR (1H, 31P, and 77Se), and single crystal X-ray diffraction. In addition, tetranuclear zinc clusters [Zn4(μ4-Se){Se2P(OPr)2}6], and [Zn4(μ4-O){Se2P(OR)2}6] (R = Et, iPr) also are synthesized and characterized. Solution studies of both [M{Se2P(OEt)2}2]∞ and [M2{Se2P(OiPr)2}4] (M = Zn, Cd) which display a monomer-dimer equilibrium in solution were performed by VT 31P NMR in CD2Cl2. |
