Homoleptic manganese(II)-azide layer: Synthesis, structural characterization and magnetic properties

摘要

A host-guest compound ((MV)[Mn(N3)4]}_n (1), where MV~(2+) (methylviologen dication) is generated in situ through the decarboxylation of 4,4'-dipyridinio-N,N'-diacetate, has been synthesized and characterized by X-ray crystallography and magnetic measurements. This is the first homoleptic two-dimensional Mn-azide compound, which contains single μ_(1,3)-azide bridged Mn(II) square layers with the organic MV~(2+) cations intercalated between the inorganic layers. Magnetic studies show antiferromagnetic interactions between adjacent metal ions (J = -4.4 cm~(-1)), and the symmetric feature of the structure precludes the possibility of spin canting in this compound.
