Ferrimagnetic-like ordering in a unique three-dimensional coordination polymer featuring mixed azide/carboxylate-bridged trinuclear manganese(II) clusters as subunits

The crystal structure of the coordination polymer [Mn-3(N-3)(2)(nta)(4)(H2O)(2)] n (nta = nicotinate) consists of trinuclear subunits bridged by mixed mu -1,1-azide and mu -carboxylate-O, O groups, which are linked by mu (3)-nta-N, O, O ligands into a three-dimensional network exhibiting ferrimagnetic-like ordering.
