Abstract

Novel chiral dinuclear complexes of Δ, Δ - [Ni2II ((R) -Hsalbn) ((R) -salbn) (MeCN)2] (ClO4) · 2 MeCN (1) and Λ, Λ - [Fe2III ((R) -salbn)2 (OMe)2] · Et2 O · H2 O (2) ((R)-H2salbn = N,N′-disalicylidene-(R)-1,1′-binaphthyl-2,2′-diaminate) were prepared. X-ray crystal structure analyses revealed that both complexes crystallized in chiral space groups of P212121 and P41212, respectively. In 1, two Ni(II) ions with Δ configuration are bridged by phenoxo groups of (R)-salbn, while in 2 μ2-methoxo ions bridge two Fe(III) ions leading to the Λ absolute configuration. Dc magnetic susceptibility measurements suggested antiferromagnetic interactions operative in 1 and 2.
