Two Trihydrazine‐Bridged Cobalt(II) Chain Compounds Exhibiting Antiferromagnetic Ordering and Single‐Chain Magnetic Behavior

Two new trihydrazine bridged Co(II) chain compounds have been synthesized and magnetically characterized. The two compounds are both composed of [Co(N2H4)3](2+) chains. One exhibits antiferromagnetic ordering behavior while the other behaves as a single-chain magnet (SCM) at low temperature.
