The preparation and characterisation of the new, potentially octadentate, ligand 1,2,4,5-tetrakis(3-(2-pyridyl)pyrazol-1-yl-methyl)benzene (L-2) is reported. This and two related ligands, 1,2-bis(3-(2-pyridyl)pyrazol-1-ylmethyl)benzene.(L-1) and hexakis (3-(2-pyridyl)pyrazol-1-ylmethyl)benzene (L-3) were reacted with zinc(II) acetate to give complexes in which pairs of ligand arms chelate to Zn(OAc) units. The X-ray crystal structures of [Zn(L-1)(OAc)]PF6 and [Zn-2(L-2)(OAc)(2)](BPh4)(2) are reported. (C) 2002 Elsevier Science B.V. All rights reserved.
