The formation of the new nickel o-xylyl derivatives NiCl(η1-CH2C6H4CH 3)(PMe3)2, 1, NiCl(η3-CH2C6H4CH 3)(PMe3), 2, and Ni3(η1-CH2C6H4CH 3)4(PMe3)2-(μ 3-OH)2, 3, is reported. A crystal structure determination on 3 shows the complex crystallizes in the space group P1 with a = 10.428 (2) A?, b = 12.646 (3) A?, c = 16.551 (3) A?, α = 70.68 (2)°, β = 79.54 (1)°, γ = 69.20 (2)°, V = 1920.4 A?3, and Z = 2. The molecule possesses a distorted trigonal-bipyramidal Ni3(OH)2 core with the Ni(II) ions in a distorted square-planar environment. Apart from the hydroxo ions, the coordination sphere of the nickel(II) ions is completed by two o-xylyl groups for one of the Ni(II) and by one alkyl group and one PMe3 ligand for the others.
