Synthesis, crystal structures, and magnetic properties of six transition metal phosphonates

Six new complexes have been quantificationally investigated for magnetic properties. There are abundant water molecules existing in the complexes with different aggregation modes.

Synthesis, structures, luminescent and molecular recognition properties of three new alkaline earth metal carboxyphosphonates with a 3D supramolecular structure

Three new alkaline earth metal carboxyphosphonates with a 3D supramolecular structure, namely, Ca[(H₃L)(H₂O)] (1), Sr[(H₃L)(H₂O)₂] (2) and Ba₂[(H₃L)₂(H₂O)₄] (3) have been hydrothermally synthesized. The luminescent and molecular recognition properties of compounds 1–3 were investigated.

Exploring the coordination chemistry of bifunctional organoarsonate ligands: syntheses and characterisation of coordination polymers that contain 4-(1,2,4-triazol-4-yl)phenylarsonic acid

The syntheses, crystal structures, luminescent and magnetic properties of five triazol-phenylarsonic acid-based M(ii) coordination polymers are reported (M = Co, Cu, Mn, Cd).

Alkaline-earth metal phosphonocarboxylates: synthesis, structures, chirality, and luminescence properties

Six new alkaline-earth metal carboxyphosphonates [Mg(H2O)(H2PMIDA)] (1), [Sr(H2O)(H2PMIDA)] (2), [Sr2(H2O)(PMIDA)] (3), [Sr2(HPO4)(H2PMIDA)] (4), [Ba2(HPO4)(H2PMIDA)] (5), and [Ba2(H2O)(H2PMIDA)2] (6) (H4PMIDA = N-(phosphonomethyl)iminodiacetic acid) have been synthesized solvothermally in order to study the coordination behavior of H4PMIDA towards alkaline-earth metal ions (Mg(2+), Sr(2+), and Ba(2+)) and the structural features of the resulting polymeric compounds. The newly synthesized compounds have been characterized by elemental analysis, UV-Vis spectrometry, IR spectroscopy, thermogravimetry analysis, solid state (31)P MAS NMR, powder X-ray diffraction analysis and single crystal X-ray diffraction techniques. The single crystal structure analysis revealed structural variability of the prepared compounds. Compounds 1, 2, 4 and 5 are three-dimensional with the H2PMIDA skeletons connecting the inorganic parts to each other, whereas compound has a layered structure. Compounds 2, 4 and 5 contain helical structural motifs. In addition, the extrinsic luminescent properties of Eu(III)- and Tb(III)-doped compounds 1, 4 and 5 have also been studied.
