TL;DR: A series of metal-organic hybrid compounds were synthesized using two new phosphonic acids, pyridyl-4-phosphonic acids and p-xylylenediphosphonic acid, which shows different ligation behavior toward the three divalent metal ions.
Abstract: A series of metal-organic hybrid compounds were synthesized using two new phosphonic acids, pyridyl-4-phosphonic acid and p-xylylenediphosphonic acid (H2O3PCH2C6H4CH2PO3H2) The phosphonic acid ligands have been synthesized from their corresponding bromides following two different types of reactions The reaction of pyridyl-4-phosphonic acid with three different divalent metal salts results in the formation of molecular structures of different dimensionality The reaction of Cu(II) with the phosphonic acid under hydrothermal conditions yields a three-dimensional (3D) open framework structure having the molecular formula [Cu4(NC5H4−PO3)4(H2O)10] (1) The reactions with Mn(II) and Zn(II) salts with the same phosphonic acid resulted in a two-dimensional layered and a dinuclear compound with molecular formulas [Mn3(NC5H4−PO3)4(H2O)6(ClO4)2] (2) and [Zn2(NHC5H4−PO3H)2Cl4] (3), respectively Compound 1 crystallizes in the triclinic crystal system having space group P1 with structural parameters a = 74564(15)
