Abstract
A new azido-bridged Mn(II) coordination polymer, [MnL(N 3) 2]n ( 1) (L = (E)-3-(dimethylamino)-1-(pyridin-2-yl)prop-2-en-1-one), has been synthesized and characterized by elemental analysis, IR, single crystal X-ray diffraction and magnetic measurement. X-ray analysis shows that complex 1 is a 2D network with (6, 3) layers, in which double end-on (EO) azido-bridged dimers are linked by single end-to-end (EE) azido bridges. Magnetic susceptibilities of 1 were measured under a magnetic field of 2 KOe applied over the temperature range 300–1.8 K. The analysis of magnetic data indicates that the EO- and EE-azido bridges mediate the ferromagnetic and antiferromagnetic exchange interactions, respectively, with the antiferromagnetic coupling between Mn(II) ions dominating the magnetic properties of 1.
