ABSTRACT
The title compound, [Cu8(C4H9O)4(C4F9O)4], crystallizes in the monoclinic space group, P21/n and contains a self-assembly of two C16H18Cu4F18O4 units linked by bridging tert-butyl groups [Cu-O bonds of length 2.3779â
(15) and 2.4248â
(15)â
Å], generating a centrosymmetric dimer. The asymmetrical unit, C16H18Cu4F18O4, 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 2.7108â
(4) to 2.7612â
(4)â
Å and Cu -Cu-Cu angle values close to 90° [ranging from 89.459â
(10)° to 90.025â
(11)°]. These dimers are further linked by weak C-Hâ¯F and Fâ¯F inter-actions. As is commonly encountered in perfluorinated tert-butyl groups, one of the CF3 groups is disordered and was refined with two equivalent conformations with occupancies of 0.74â
(3) and 0.26â
(3).
