Oxoselenide triangular molybdenum clusters: Synthesis and characterization of [Mo3SeO3(acac)3(py)3]PF6
摘要:
New cluster complex [Mo3SeO3(acac)(3)(py)(3)](+) was obtained by ligand substitution in the aqua complex [Mo3SeO3(H2O)(9)](4+). Crystal structure was determined for [Mo3SeO3(acac)(3)(py)(3)]PF6 center dot C6H5CH3. The complex was characterized by Se-77 NMR, electrospray mass-spectrometry, and cyclic voltammetry. DFT calculations were used to confirm the assignment of chemical shift and to study Mo-Mo bonding in the cluster core. (C) 2011 Elsevier B.V. All rights reserved.
