N2 - In the last decade, there has been a great interest in the phosphonic acid-based molecular complexes and coordination polymers. Because the M-O-P bonds are 1.5 times stronger then M-O-C bonds in carboxylates, phosphonates were used in the role of molecular precursors for the synthesis of new materials, such as polynuclear metal phosphonates, layered compounds, and porous metal-organic frameworks, with a wide range of properties and different applications. Phosphonate mononuclear complexes or molecular clusters with paramagnetic metal cations are very interesting objects because of their magnetic properties. We synthesized and isolated new molecular complexes and coordination polymers of AIPA ((1-amino-1-methyl-ethyl)phosphonic acid) and NaxSAA, x = 1, 2 (sodium hydrogen (2-{[(E)-(2-hydroxyphenyl)methylidene]amino}propan-2-yl)phosphonate, disodium hydrogen (2-{[(E)-(2-oxidophenyl)methylidene]amino}propan-2-yl)phosphonate) ligands with Fe3+, Ni2+, Co2+, Dy3+, and Gd3+. Their properties were studied by a variety of physicochemical methods including structural analyses by single-crystal X-ray diffraction methods. Their magnetic properties were studied on a SQUID magnetometer. Among the most interesting results obtained in this study are isolation and characterization of hexanuclear iron(III) phosphonate Fe6(NH3(CH3)2CPO3)12(OH)6].31H2O, a 1D coordination polymer of Fe with the SAA ligand, a series of heptanuclear Co2+ phosphonates with a Star-of-David structural motif, and a coordination polymer of Ni2+ with SAA ligands. Beside that, mononuclear isostructural complexes of Ni2+ and Co2+ with AIPA were obtained and characterized. The presence of non-coordinated amino groups in the complexes with AIPA makes these compounds potentional precursors for the synthesis of new extended structures.
