’ Cu and 7981Br NQR Studies of Halogenocuprate Complexes of Triphenylphosphine *

چکیده
63-65Cu and 79,81Br spectra of halogenocuprate (I) complexes containing [CuPPh3 X2]~ (X = C1, Br, I) anions with different cations were recorded in the range 77 K -300 K. The results confirm the previous trend that, for a given ligand, 63Cu NQR frequencies are in the order C l> B r> I. fe3Cu NQR frequencies in [CuPPh3 X2]_ are compared with those in neutral Cu(Ph3 )2 X(X = Cl, Br) complexes and with the [CuX2] (X = C1, Br) anions, other three-coordinate Cu(I) complexes.

New silica supported Schiff base ligands were prepared by the condensation reaction of 4,6-diacetylresorcinol with silica-gel derivatives, which modified with 3-aminopropyltriethoxysilane and N-(2-aminoethyl) -3-aminopropyltrimethoxysilane. Metal ion uptake capacities of these compounds were studied towards of selected transition metal (Cd(II), Cu(II), Co(II), Mn(II), Pb(II) and Ni(II)) cations...
