Bis(N‐acetyltriethylphosphaneiminium)‐tetraacetato‐dichloro‐dicuprate(II), [MeC(O)N(H)PEt 3 ] 2 [Cu 2 (O 2 C–Me) 4 Cl 2 ] The title compound has been prepared by the reaction of Me 3 SiNPEt 3 with [Cu 2 (O 2 C–Me) 4 ] and MeC(O)Cl in dichloromethane solution to give colourless crystals which include four molecules CH 2 Cl 2 per formula unit. The complex is characterized by IR spectroscopy and by a crystal structure determination. [MeC(O)N(H)PEt 3 ] 2 [Cu 2 (O 2 C–Me) 4 Cl 2 ] · 4 CH 2 Cl 2 : Space group P2 1 /n, Z = 2, lattice dimensions at –70 °C: a = 794.1(1), b = 2356.9(6), c = 1327.3(2) pm; β = 91.00(1)°; R 1 = 0.0597. The structure consists of N‐acetyltriethylphosphaneiminium cations and dianions [Cu 2 (O 2 C–Me) 4 Cl 2 ] 2– which form an iontriple with N–H…Cl hydrogen bridges.
