Syntheses, structures and magnetic properties of 1-D coordination polymers containing both dicyanamide and 2-pyrrolidone

Structures of two 1-D coordination polymers, [MII(pyr)2(N(CN)2)2] (M=Mn (1), Co (2), pyr=2-pyrrolidone), have been determined. They are isomorphous and belong to monoclinic space group, Cm with Z=2. The magnetic properties of two compounds (2–300 K) show the existence of weak antiferromagnetic exchange interaction between paramagnetic centers along chains.
