The assembly of pentanuclear nickel(ii) complexes from asymmetric compartmental ligands and bearing μ3-OH bridges

Abstract

The asymmetric di-aminic compartmental ligands HL⁵–HL⁷ form pentanuclear nickel(II) complexes in which the core is assembled from two dinuclear [Ni₂L] units which are each linked to the third Ni atom by bridging μ₃-hydroxo groups; the crystal structure of [Ni₅(L⁵)₂(OAc)₆(OH)₂], 1 [HL⁵ is the proligand 2-{[(2-dimethylaminoethyl)ethylamino]methyl}-6-ethyliminomethyl-4-methylphenol] is reported.
