Abstract

By using a flexible multidentate carboxylate linker 4,4′,4′′-(((2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))tribenzoic acid (H3L), four novel coordination polymers [Mn7L4(DMF)4(H2O)4Cl2]·10(H2O) (1), [Cd7L4(DMF)4(H2O)4Cl2]·10(H2O) (2), [Co7L4(DMF)4(H2O)4(OH)2]·11(H2O) (3), and [Co4L2(DMF)2(H2O)4Cl2]·4(DMF)·3(H2O) (4) were obtained and characterized by single-crystal X-ray diffraction, thermogravimetric and magnetic studies. Compounds 1–3 are isomorphous, built upon a 12-connecting linear M7 cluster and a 3-connecting L3− ligand to form a polycatenated 3D network. 4 comprises of 3-connecting trigonal M2 clusters and L3− linkers to form a 2D layered structure with hcb topology. The magnetic studies of the M7-cluster compounds 1 and 3 show the presence of antiferromagnetic interactions between the M2+ ions in 1 and 3.
