Deskripsi

Ferromagnetic coupling exists in an uneven chain-like copper(II) complex with both end-on azido and <i>syn</i>-<i>syn</i> carboxylato bridges, (Cu<sub>3</sub>(L)<sub>2</sub>(N<sub>3</sub>)<sub>4</sub>(H<sub>2</sub>O)<sub>3</sub>)<sub>n</sub> (<b>1</b>, HL = 6-hydroxynicotinic acid). It is the first example of one-dimensional (1D) chain-like copper(II) coordination polymer showing both metamagnetic behavior and long-range magnetic ordering (<i>T</i><sub>c</sub> = 6.7 K), thanks to the interchain hydrogen bonds, which make a three-dimensional (3D) supramolecular array of the entire molecular structure and mediate the interchain antiferromagnetic interaction.
