Abstract:By combining trans-4-styrylprydine (tsp) with azide system, we obtained two rare 1D cis-EE-azido-bridged compounds of [M-2(N-3)(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.
