摘要
By combining trans-4-styrylprydine （tsp） with azide system, we obtained two rare 1D cis-EE-azido-bridged compounds of [Mz（N3）4（tsp）4（H2O）2] [M = Mn （1）, Co （2）]. The magnetic study reveals that metal ions are anti-ferromagnetically coupled by cis-EE-azido-bridges and they show weak ferromagnetism below 4.0 K （1） and 4.2 K （2） due to the spin-canting caused by asymmetric magnetic interaction.
