Two-dimensional metal azides have been synthesized solvothermally, in which heptanuclear Ln@Co6 clusters are formed encapsulating a nonacoordinate D-3h Ln(III) ion in a Co6 cage. The connection of azide ligands links these clusters to form a 2D metal azide layer. Magnetic studies indicate the presence of ferromagnetic interactions in these compounds.
Two-dimensional metal azides [LnCo(9)(Pzc)(6)(OH)(3)(N-3)(11)-2(CH3OH)-2H(2)O]n (Ln = Gd for 1 and Dy for 2) have been solvothermally prepared. In 1 and 2, a heptanuclear Ln@Co6 cluster is formed in which a nonacoordinate D-3h Ln(III) ion is encapsulated in a Co6 cage. The heptanuclear Ln@Co6 clusters are linked by disordered Co-3(N-3)(11) units through the connection of the azide to give a 2D metal azide layer. Magnetic studies indicate ferromagnetic magnetic interactions between the ions in 1 and 2.
