Example of a single trans-azido-bridged Mn(II) chain: synthesis, structural and magnetic characteristics

The synthesis of a trans coordinated 1-D μ1,3-azido-Mn(II) chain compound of the formula [Mn(L)(N3)PF6]n (L=2,13-dimethyl-3,6,9,12,18-pentaazabicyclo{12.3.1}octadeca-1,(18),2,12,14,16-pentaene) is reported. Its crystal structure consists of 1-D arrays of Mn(II) units linked by single End-to-End azido bridges in trans position. Magnetic susceptibility measurements indicate long range antiferromagnetic correlation between the Mn(II) centres below 30 K (J=−4.8 cm−1, H=−J∑ SiSi+1). The solid state EPR behaviour confirms that [Mn(L)(N3)PF6]n consists of 1-D Mn(II) arrays magnetically well isolated from the neighbouring chains.
