Syntheses and Crystal Structures of Novel Chalcogenido-bridged Niobium Copper Clusters In the presence of tertiary phosphines, the reaction of NbCl5 and Copper(I) salts with Se(SiMe3)2 (E = S, Se) affords the new chalcogenido-bridged niobium-copper cluster compounds (1) and [NbCu4Se4Cl (PPh3)4] (2). Using E(R)SiMe3 (E = S, Se, R = Ph, nPr) instead of the bisilylated selenium species leads to the compounds
