Syntheses and magnetic properties of three Mn(II) coordination polymers based on a tripodal flexible ligand

The solvothermal reaction of Mn(II) and tri(2-carboxyethyl)isocyanurate (H3tci) with or without the presence of 1,2-bis(4-pyridyl)ethylene in different solvents leads to the generation of three novel Mn(II) coordination polymers, namely, Mn3(tci)2(DMF)2(H2O)2 (1), [Mn3(tci)2(DMA)4]·2DMA (2) and [Mn(Htci)(bpe)0.5]·H2O (3). 1 features a 3D porous coordination polymer constructed by {Mn–(μ2–O)–Mn}n chains linked by the flexible arms of tci ligands. 2 features a 2D CdI2 topological layer based on trinuclear Mn(II) clusters as nodes. 3 is a 3D pillar-layered structure. The magnetic properties of these complexes have also been reported.
