title: Alkynyl complexes of high-valence clusters. synthesis and luminescence properties of [Mo6I8(C≡CC(O)OMe)6]2-, the first complex with exclusively organometallic outer ligands in the family of octahedral {M6X8} clusters.
abstract: The reaction of [Mo6I14](2-) with methyl propiolate HC≡CC(O)OMe in the presence of Ag(+) and Et3N yielded the new luminescent complex [Mo6I8(C≡CC(O)OMe)6](2-), the first fully organometallic complex in the family of octahedral {M6X8} clusters. The cluster was crystallized as tetraphenylphosphonium salt and characterized by X-ray single-crystal diffraction and elemental analyses, mass spectrometry, (13)C NMR, UV-vis, and luminescence spectroscopies.
