The protonation constants of N-(4-vinyl)benzyl ethylenediamine (L1), 1-(4-vinyl)benzyl diethylenetriamine (L2), 4-(4-vinyl)benzyl diethylenetriamine (L3), and the stability constants of their Cu(II) and Zn(II) complexes have been potentiometrically determined. The crystal structures of [Cu(L1)2][ClO4]2 and [CuL2(NO3)2]·CH3CO2C2H5 are reported. [Cu(L1)2][ClO4]2 crystallizes in the monoclinic system with space group P21/c, having lattice parameters a = 12.48(2), b = 12.062(16), c = 9.188(15) A?, β = 97.46(7)°, and Z = 2. [CuL2(NO3)2]·CH3CO2C2H5 crystallizes in the monoclinic system with space group P21/n, having lattice parameters a = 10.239(2), b = 9.177(1), c = 24.096(4) A?, β = 95.99(1)°, and Z = 2. Kinetic studies show that the Cu(II)-containing cross-linked polymers made from incorporating [Cu(L1)2]X2 and [CuL3]X2 (X = ClO4-, NO3-) catalyze the hydrolysis of 4-nitrophenyl phosphate with first-order rate constants 1.33 x 10-5 and 1.04 x 10-6 s-1, respectively, at 55°C and pH 8.5.
