Three new tetrahedral rhenium cluster compounds [Re4Se4(PMe2Ph)(4)Br-8]center dot 1.5CH(2)Cl(2) (1), [Re4Te4(PMe2Ph)(4)Br-8]center dot CH2Cl2 (2), and [Re4Te4(PMe2Ph)(4)Cl-8]center dot CH2Cl2 (3) have been synthesized by the reaction of the corresponding precursor chalcohalide complexes [Re(4)Q(4)(TeX2)(4)X-8] (X = Br, Q = Se (for 1), Te (for 2); X=Cl, Q=Te (for 3)) with dimethylphenylphosphine in CH2Cl2. All compounds have been characterized by X-ray single-crystal diffraction and elemental analyses, IR and P-31 NMR spectroscopy. P-31 NMR spectroscopy indicates the formation of isomers in solution, confirmed by single-crystal X-ray analysis.
