Highly soluble Cu(I)-acetonitrile salts as building blocks for novel phosphorus-rich organometallic-inorganic compounds

The synthesis of the air-stable and highly soluble Cu(I-acetonitrile salts [Cu(CH3CN)(3.5)][FAL] (1) ([FAL] = FAL{OC(C6F10)(C6F5)}(3)) and [Cu(CH3CN)(4)][TEF] (2) ([TEF] = Al{OC(CF3)(3)}(4)) is presented. Compound 1 reacts with the organometallic polyphosphorus complexes [Cp2Mo2(CO)(4)(eta(2)-P-2)] (A) and [(Cp*Fe(eta(5)-P-5)] (B) and salt 2 reacts with B to form one new (3) and three unprecedented (4-6) phosphorus-rich Cu(I) dimers with the general formulas [Cu-2(mu,eta(1):eta(1)-A)(2)(eta(2)-A)(2)][FAL](2) (3), [Cu-2(mu,eta(1):eta(1)-A)(2)(eta(1)-CH3CN)(4)][FAL](2) (4), [Cu-2(mu,eta(1):eta(1)-B)(2)(eta(1)-CH3CN)(4)][FAL](2) (5) and [Cu-2(mu,eta(1):eta(1)-B)(2)(eta(1)-CH3CN)(4)][TEF](2) (6).
