Sulfonylcalix[4]arene as a Bis-Tridentate Facial Ligand: Syntheses and Structures of Dinuclear Complexes, [M2(L)(H2O)2(dmf)4] (M = Co(II), Ni(II) ; H4L = <i>p</i>-<i>tert</i>-Butylsulfonylcalix[4]arene)

Abstract

Abstract Cobalt(II) and nickel(II) complexes with a tetraanionic ligand of p-tert-butylsulfonylcalix[4]arene were synthesized and their X-ray structures show that the calixarene acts as a bis-tridentate dinucleating ligand with the 1,2-alternate conformation.
