STRUCTURES AND PROPERTIES OF [CU4(C3X5)3]2- (X = S AND SE) CLUSTER ANION COMPLEXES

[CiMCgXgJg]2“(X = S and Se) [CgS52‘= 4, 5-dimercapto-l, 3-dithlole-2-thionate(2-) and CoSe^ = 4, 5-di-(hydroseleno)-l, 3-diselenole-2-selonate(2-)] cluster anion complexes were prepared. Molecular interactions among the anion moieties through S~S and Se-Se contacts in the solid state were deduced from X-ray structure analysis and electronic reflectance spectra. They reacted with [FeCp2]+and [FeCp2]+cations (Cp and Cp = the cyclopentadienyl and decamethylcyclopentadienyl anions, respectively) to give partially oxidized species with ligand-centered oxidation. They behave as semiconductors with electrical conductivities of lx(10“3-10-7) S cm-1 measured for the compacted pellets. © 1992, Taylor & Francis Group, LLC. All rights reserved.
