Thanks to such bulky ion-walls, each chain is not only structurally separated with a nearest inter-chain metal * * * metal distance of 14.4A˚ (Mn * * * Ni) but also magnetically extremely well isolated. This magnetic isolation and the ferromagnetic interactions between S = 3 anisotropic units constituting the chain play key roles that induce single-chain magnet behavior in this system.
