Abstract

Novel chiral dinuclear complexes of Δ, Δ - [Ni₂^II ((R) -Hsalbn) ((R) -salbn) (MeCN)₂] (ClO₄) · 2 MeCN (1) and Λ, Λ - [Fe₂^III ((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.
