A Three-Dimensional Homometallic Molecular Ferrimagnet

Abstract

Chains of fused NiII octahedral units form a 3D network and thereby the first example of a homometallic 3D ferrimagnet. The material was characterized by X-ray analysis and a low-temperature magnetic study. The structure features an infinite -Ni-(μ3-OH)-Ni2- chain and the spin of adjacent Ni centers alternates between S=1 and S=2 (see picture).
