Abstract EN
Three two-dimensional (2D) and 3D supramolecular coordination architectures based on ternary M(II)-dicyanamide-2-hydroxypyridine systems, [Co(hmpH)2(dca)2] (1), [Cu(hmpH)2(dca)2] (2), and [Mn(hepH)2(dca)2] (3) (dca = dicyanamide, hmpH = 2-(hydroxymethyl)pyridine, hepH = 2-(hydroxyethyl)pyridine), have been synthesized.
1 is a mononuclear Co(II) complex.
The mononuclear units are interlinked into a 2D (4,4) hydrogen-bonded layer via O–H⋯N hydrogen bonds between the hydroxyl groups and the noncoordinating nitrile ends.
These 2D layers are further extended into a 3D supramolecular architecture via the interlayer pyridyl-pyridyl stacking interaction.
2 has a 1D coordination chain structure formed by the double μ1,5-dca bridged dinuclear [Cu2(μ1,5-dca)2(hmpH)2] unit and the μ1,3-dca bridges via weak Cu–N coordination, and these 1D coordination chains are further extended into 2D hydrogen-bonded layers via strong O–H⋯N hydrogen-bonding interaction between the hydroxyl groups and the noncoordinating nitrile ends.
3 is a 2D (4,4) coordination network made of 1D [Mn(hepH)(μ1,5-dca)] helical chain units and interchain double (μ1,5-dca) bridges.
Pairs of [Mn(hepH)(μ1,5-dca)] helical chains are interlinked by the double (μ1,5-dca) bridges into a racemic coordination layer structure, which is further extended into a 3D hydrogen-bonded network.
Magnetic studies reveal that weak antiferromagnetic exchange occurs in 3.
