A one-pot synthesis of a paramagnetic high-nuclearity nickel(II) cluster: an octadecanuclear NiII16NaI2 metal aggregate

An unusual NiII16NaI2 cluster which features formate as a bridging clamp between two octanuclear nickel cages is reported; preliminary magnetic studies exhibit paramagnetic low-lying states resulting from dominating antiferromagnetic interactions between the nickel(II) centers.
