A phen–terpy conjugate whose chelate coordination axes are orthogonal to one another and its zinc complex

Abstract

A new highly rigid ditopic ligand has been prepared which consists of a terpy fragment connected through its 4′ position to the 3 position of a phen nucleus via a 1,4-phenylene linker. The chemical structure of the presently reported two-chelate ligand is such that the coordination axes of the two chelates are orthogonal to one another. The reaction of this phen–terpy conjugate with Zn²⁺ affords in good yield a dimeric structure, as shown by ES-MS and ¹H NMR spectroscopies.
