Title: 1-D and 2-D homoleptic dicyanamide structures, [Ph{sub 4}P]{sub 2}{Co{sup II}[N(CN){sub 2}]{sub 4}} and [Ph{sub 4}P]{M[N(CN){sub 2}]{sub 3}} (M = Mn, Co).

Abstract

The homoleptic complexes [Ph{sub 4}P]{sub 2}{l_brace}Co[N(CN){sub 2}]{sub 4}{r_brace} and [Ph{sub 4}P]{l_brace}M[N(CN){sub 2}]{sub 3}{r_brace} [ M = Co, Mn] have been structurally as well as magnetically characterized. The complexes containing {l_brace}M[N(CN){sub 2}]{sub 4}{r_brace}{sup 2-} form 1-D chains, which are bridged via a common dicyanamide ligand in {l_brace}M[N(CN){sub 2}]{sub 3}{r_brace}{sup -} to form a 2-D structure. The five-atom [NCNCN]{sup -} ligands lead to a {sup 4}T{sub 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.
