Abstract

The two-coordinate cationic Ni(1) bis-N-heterocyclic carbene complex [Ni(6-Mes)(2)]Br (1) [6-Mes = 1,3-bis (2,4,6-trimethylphenyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene] has been structurally characterized and displays a highly linear geometry with a C-Ni-C angle of 179.27(13)degrees. Density functional theory calculations revealed that the five occupied metal-based orbitals are split in an approximate 2:1:2 pattern. Significant magnetic anisotropy results from this orbital degeneracy, leading to single-ion magnet (SIM) behavior.
