Tetrakis[μ(2)-1,1,1,3,3,3-hexafluoro-2-(trifluoromethyl)propan-2-olato]tetrakis(μ(3)-2-methylpropan-2-olato)octacopper(I)
The title compound, [Cu(8)(C(4)H(9)O)(4)(C(4)F(9)O)(4)], crystallizes in the monoclinic space group, P2(1)/n and contains a self-assembly of two C(16)H(18)Cu(4)F(18)O(4) units linked by bridging tert-butyl groups [Cu—O bonds of length 2.3779 (15) and 2.4248 (15) Å], generating a centrosymmetric dime...

Sumario: | The title compound, [Cu(8)(C(4)H(9)O)(4)(C(4)F(9)O)(4)], crystallizes in the monoclinic space group, P2(1)/n and contains a self-assembly of two C(16)H(18)Cu(4)F(18)O(4) units linked by bridging tert-butyl groups [Cu—O bonds of length 2.3779 (15) and 2.4248 (15) Å], generating a centrosymmetric dimer. The asymmetrical unit, C(16)H(18)Cu(4)F(18)O(4), contains an almost square-planar arrangement of the four Cu atoms linked by bridging tert-butyl and perfluorinated tert-butyl groups with Cu—Cu distances ranging from 2.7108 (4) to 2.7612 (4) Å and Cu —Cu—Cu angle values close to 90° [ranging from 89.459 (10)° to 90.025 (11)°]. These dimers are further linked by weak C—H⋯F and F⋯F interactions. As is commonly encountered in perfluorinated tert-butyl groups, one of the CF(3) groups is disordered and was refined with two equivalent conformations with occupancies of 0.74 (3) and 0.26 (3). |
