Pj. Alonso et al., SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF THE FIRST HOMOLEPTIC ORGANOMETALLIC NICKEL(III) COMPOUND, Chemical communications, (5), 1997, pp. 503-504
The homoleptic, square-planar, d(7), 15-electron species [NBu(4)][Ni-I
II(C6Cl5)(4)] 2 is obtained by low-temperature oxidation of [NBu(4)](2
)[Ni-II(C6Cl5)(4)] 1 with Cl-2.
