Abstract
Complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) of 5,11,17,23-tetra-tert-butyl-25,27-diethoxy-carboxymethoxy-26, 28-dihydroxycalix[4]arene were synthesized for the first time and were well characterized. Totally six dinuclear complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) of calix[4]arene derivatized with two pendants possessing terminal -COOH functions at two of its alternate phenolic -OH groups were synthesized for the first time and were well characterized. © 2004 Elsevier B.V.
