description

Abstract Five structural kinds of nickel hydrogen-bonded networks containing hydrotris(3,5-dimethylpyrazolyl)borate ligands (Tp∗) have been elucidated by X-ray diffraction, [Tp∗Ni(OH2)3][(p-NO2C6H4O)2PO2] (4), [Tp∗Ni(OH2)3][Me2PO2]·Me2P(O)OH (5), [Tp∗Ni(OH2)3][(nBuO)2PO2]·0.5H2O (6), [(Hpz)Tp∗Ni(OH2)2][(Ph)PO2OH] (7) and [Tp∗Ni(OH2)2(Me2PO2)] (8). The most relevant supramolecular feature of complexes 4–8 is all of them form coordination networks based on hydrogen bonds between water molecules and phosphate, phosphonate or phosphinate anions. These hydrogen bonds are formed within the monomer units in addition to connect monomers along the chains. Their behaviors in solution were investigated by one- and two-dimensional 1H NMR techniques.
