title: Two trihydrazine-bridged cobalt(II) chain compounds exhibiting antiferromagnetic ordering and single-chain magnetic behavior.
abstract: 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.
