title: Bis(tert-butyl isocyanide-κC)[4-fluoro-N-({2-[N-(4-fluorophenyl)carboximidoyl]cyclopenta-2,4-dien-1-ylidene}methyl)anilinido-κ2N,N']copper(I).
abstract: The solid-state structure of the title compound, [Cu(C(19)H(13)F(2)N(2))(C(5)H(9)N)(2)], shows that the Cu(I) centre adopts a distorted tetrahedral coordination geometry, being coordinated by two N atoms of the 6-aminofulvene-2-aldimine (AFA) chelating ligand and by the bridgehead C atoms of the two isocyanide ligands. The cyclopentadienyl and imine components of the AFA ligand are approximately coplanar, with an angle between the planes of 5.00 (3)°. The Cu atom lies 0.6460 (3) Å above the imine plane defined by the N and C atoms of the seven-membered metallocycle. There is also an uncommon C-H···Cu anagostic interaction, with an intramolecular Cu···H distance of 2.67 Å, which is less than the sum of the van der Waals radii.
