Abstract

Cyanidometallate complexes are highly versatile building units for the generation of functional porous materials. Here we report five new pillared Hofmann layer compounds incorporating the tetracyanidometallates [MoO(CN)4]2− and [MnN(CN)4]2−. These metalloligands, which are new to this class of materials, have been combined with divalent 1st-row transition metals to produce Hofmann layers that are linked into three-dimensional frameworks by ditopic bridging dipyridyls. We report the structures and anomalous thermal expansion properties of five new materials: [Mn(H2O)(bpy)½{MoO(CN)4(bpy)½}]·2H2O (1), [Mn(H2O)(bpy)½{MnN(CN)4(bpy)½}]·2H2O (2), [Fe(H2O)(bpy)½{MnN(CN)4(bpy)½}]·2H2O (3), [Co(H2O)(bpy)½{MnN(CN)4(bpy)½}]·2H2O (4) and [{Mn(H2O)2}½{Mn(bpa)2}½{MoO(CN)4(bpa)½}]·MeOH (5), (where bpy = 4,4′-bipyridine and bpa = 4,4′-bipyridylacetylene).
