Exceptional temperature-dependent coordination sites from acylamide groups

Abstract

Herein, through altering the reaction temperature, the coordination mode of the acylamide ligand is well controlled with or without the oxygen coordination site. The resulting two new coordination polymers have the formulas Cd₃(L)₂(bdc)₃·4(H₂O) (1) and Cd(L)(bdc)·2(H₂O) (2) (L = N¹,N⁴-bis(pyridin-3-ylmethyl)terephthalamide, H₂bdc = terephthalic acid).
