1-D and 2-D homoleptic dicyanamide structures, [Ph4P]2[CoII[N(CN)2]4] and [Ph4P][M[N(CN)2]3] (M = Mn, Co)

The homoleptic complexes Ph(4)P](2)CoN(CN)(2)](4)] and Ph(4)P]MN(CN)(2)](3)] M = Co, Mn] have been structurally as well as magnetically characterized. The complexes containing MN(CN)(2)](4)](2-) form 1-D chains, which are bridged via a common dicyanamide ligand in MN(CN)(2)](3)](-) to form a 2-D structure. The five-atom NCNCN](-) bridging ligands lead to weak magnetic coupling along a chain. The six NCNCN](-) ligands lead to a (4)T(1g) ground state for Co(II) which has an unquenched spin-orbit coupling that is reflected in the magnetic properties. Long-range magnetic ordering was not observed in any of these materials.
