Aminoalkyl-1,1-bis(phosphinic acids): Stability, Acid-Base, and Coordination Properties
Original language description
Four geminal bis(phosphinic acids), namely, aminomethyl-bis(H-phosphinic acid) (H2L1) and 4-aminobutyl-1-hydroxy-1,1-bis(R-phosphinic acid) with R = H (H2L2), Me (H2L3) and CH2CH2COOH (H4L4), were studied. Their acid-base properties and coordination ability towards Cu2+, Ni2+ and Zn2+ ions were studied by potentiometry, UV/Vis spectroscopy and NMR spectroscopy. The amine group in H2L1 has a lower protonation constant (log K-a = 6.79) than those found for other studied bisphosphinates (logK(a) = 10.75-11.05) with distant amine groups. The structure of [Ca(H2L2-O,O')(HL2-O,O')]Cl revealed an octahedral arrangement of the metal coordination sphere and a linear polymeric structure, which forms through eight-membered Ca(-O-P-O-)(2)Ca rings. The structure of[Cu(HL3-O,O')(2)(H2O)]center dot 5H(2)O shows two chelating bisphosphinate groups in an equatorial O-4 environment. The structure of [Cu(H0.5L3-O,O')(NO3)(0.5)]center dot 2.25H(2)O shows two different coordination environments, one is an
