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
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, C-13 NMR, UV-vis, and luminescence spectroscopies.
