Synthesis and crystal structure of a new chiral α-amino-oxime nickel(II) complex.

A dinuclear nickel complex with ()-limonene based amino-oxime ligand has been isolated and its crystal structure determined. The resolved structure of dichloridobis-{(2,5)-2-methyl-5-(prop-1-en-2-yl)-2-[(pyridin-2-yl)methyl-amino]-cyclo-hexan-1-one oxime}dinickel(II), [NiCl(CHClNO)], at 100 K has monoclinic (2) symmetry. The two Ni ions in the dinuclear complex are each coordinated in a distorted octa-hedral environment by three nitro-gen atoms, a terminal chloride and two μ bridging chlorides.
