Abstract

Polymeric (CuStBu) (1) undergoes reaction with trialkylphosphines to form the cuprous thiolato phosphine complexes [(CuS tBu)4(PR3)2] (R = Me (2a), Et (2b)) in high yield. In contrast to 2b, in polar solvents (CH2Cl 2, tetrahydrofuran), complex 2a is in equilibrium with the ion pair Cu(PMe3)4 +Cu5(StBu) 6 - (3) and other species such as (CuStBu) x(PMe3)2 (x = 6 (4), 8 (5)). Clusters 2-4 were isolated analytically pure and fully characterized in solution by multinuclear nuclear magnetic resonance (NMR) spectroscopy and in the solid state by single-crystal X-ray diffraction and 31P magic angle spinning NMR spectroscopy, while the structure of compound 5 was determined by single-crystal X-ray diffraction. Thermal analysis (TGA/DTA) and examination of the volatile byproducts suggest stepwise phosphine loss and C-S bond cleavage by isobutene elimination as the predominant thermolysis pathways of this new Cu2S precursor class.
