A high-spin tridecanuclear NiII cluster, [NiII13(N3)18(dpo)4(Hdpo)2(H2hpo)4(H2O)(MeOH)] [NiII13(N3)18(dpo)4(Hdpo)2(H2hpo)4(H2O)2] (1) (Hdpo = 1-(dimethylamino)propan-2-one oxime and H2hpo = 1-(hydroxyamino)propan-2-one oxime) with a purely azido-bridged core, is reported with dominant ferromagnetic coupling between NiII ions. The latter molecule exhibits a unique planar core topology with the largest N3− : NiII ratio reported to date.
