Abstract

Reactions of the precursors [Ni(macrocyclic ligand)]2+ with [W(CN)8]3− afford two octacyanotungstate-based assemblies, (H2L1)0.5[Ni(L1)][W(CN)8]·2DMF·H2O (L1 = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) (1) and [Ni(L2)]3[W(CN)8]2·4H2O (L2 = 3,10-dipropyl-1,3,5,8,10,12-hexaazacyclotetradecane) (2). Single crystal X-ray diffraction shows that 1 consists of anionic one-dimensional (1D) linear chains, while 2 is built of 2D graphite-like layers with (6, 3) topology. Magnetic studies reveal that both complexes exhibit metamagnetic behavior from the spin-canted antiferromagnet to the ferromagnet induced by field.
