Abstract

Four novel manganese phosphonate clusters, namely Cl@[Mn6(t-BuPO3)8(H2O)2(CH3OH)4][OH] (1), Br@[Mn6(t-BuPO3)8(H2O)2(CH3OH)4][OH]·4H2O (2), [Mn13O6(t-BuPO3)10(OH)6(CH3OH)6][Mn13O6(t-BuPO3)10(OCH3)6(t-BuPO3H2)2(H2O)4]·2CH3OH·10H2O (3) and [Mn15K2O8(t-BuPO3)10(CH3O)4(C6H5COO)4(H2O)8]·6H2O (4), have been successfully synthesized in the presence of tert-butylphosphonic acid, carboxylic acid, NBun4MnO4 and different manganese sources. These clusters were characterized by elemental analyses, IR spectroscopy, thermogravimetric (TG) analyses and single-crystal X-ray diffraction. Single-crystal structure analyses reveal that the structures of 1–4 are diverse. The structure of cluster 1 is analogous to that of cluster 2, which displays a cage-like arrangement with one halide ion (Cl−, Br−) lying inside the centre of the cave. Cluster 3 is a carboxylate-free manganese phosphonate cluster consisting of two similar Mn13 structural units. Moreover, there exist two potassium ions and fifteen manganese ions in the heterometallic cluster 4. In addition, solid-state DC magnetic susceptibility measurements indicate the existence of overall antiferromagnetic (AF) exchange interactions between the Mn ions in all clusters.

Abstract

The hydrothermal reaction of rare earth nitrates, CuCN, 1H-1,2,3-triazole-4,5-dicarboxylic acid (H3tda), and isonicotinic acid (Hina) resulted in the formation of a new series of 3d–4f heterometallic coordination polymers [LnCu(tda)(ina)2(H2O)]·3H2O (Ln = Eu (1), Tb (2), Gd (3), Dy (4), Ho (5)], H3tda = 1H-1,2,3-triazole-4,5-dicarboxylic acid, Hina = isonicotinic acid). Complexes 1–5 are isostructural and structurally characterized by elemental analysis, FT-IR spectroscopy, thermogravimetric analysis (TGA), and single-crystal powder X-ray diffraction (PXRD). Single-crystal X-ray diffraction analysis reveals that the metal cations in these compounds are firstly interconnected by H3tda ligands to produce a carpet-shaped heterometallic ring [Ln2(tda)2Cu4], and then pillared by bridging Hina molecules to form the 3D layer-pillared porous Ln(III)–Cu(II) heterometallic coordination polymers. In addition, the magnetic properties of 1–5 were also investigated in detail.
