Four novel Co(II) and Mn(II) coordination polymers with triazolyl derivate: Syntheses, crystal structures and magnetic properties

Four azido-/dca-bridged coordination polymers with PTE have been synthesized and structurally characterized. [M(PTE)2(N3)2]n (M = Mn 1 and Co 2) show isostructural 1-D chain linked by alternative double end-to-end and double end-on azido bridges. [M(PTE)2(dca)2]n (M = Mn 3 and Co 4) show isostructural 2-D dca-bridged (4,4) grid. The magneto-structural relationships are investigated in detail based on the crystal structures.
