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.

Co{sub 2}{l_brace}[N(CN){sub 2}]{sub 4}bpym{r_brace}{center_dot}H{sub 2}O (1) and M{l_brace}[N(CN){sub 2}]{sub 2}bpym{r_brace}{center_dot}H{sub 2}O [M = Mn (2a), Fe (2b), Co (2c); bpym = 2,2{prime}-bipyrimidine] have been synthesized and characterized structurally and magnetically. All of the compounds crystallize in the orthorhombic space group Pnma. The unit cell parameters for 1 are a = 16.1684(5) {angstrom}, b = 12.9860(3) {angstrom}, c = 10.4207(3) {angstrom}, and Z = 4. Compound 1 is a 2-D layered structure with water intercalated between sheets. The sheets are composed of {hor_ellipsis}M-[NCNCN]{sub 2}-M-bpym-M-[NCNCN]{sub 2}-M{hor_ellipsis} chains, which are linked together by dicyanamides. 21--c are isomorphic with the unit cell parameters amore »« less

Spontaneous magnetization in the M[N(CN){sub 2}]{sub 2} (M = Cr, Mn) weak ferromagnets

Journal Article Manson, J L ; Miller, J S ; Kmety, C R ; ... - Inorganic Chemistry

Due to stabilization of relatively strong magnetic coupling, multidimensional coordination polymers consisting of transition metal cations and the dicyanamide ligand. [N(CN){sub 2}]{sup {minus}}, are currently being studied. Homoleptic dicyanamide complexes with octahedral metal sites from 3-D rutile-type architectures. M[N(CN){sub 2}]{sub 2} (M = Co, Ni) exhibit ferromagnetic ordering at 9 and 21 K, respectively, and have been further characterized by neutron diffraction and specific heat measurements. In contrast, interpenetrating M[C(CN){sub 3}]{sub 2} (M = Mn, Fe, Co, Ni, Cu) also have rutile-type networks, but exhibit weak antiferromagnetic coupling while M = V and Cr are strongly antiferromagnetically coupled and exhibitmore »« less

While the Fe and Os complexes react with nucleophilic amines (ammonia, MeNH{sub 2}, Me{sub 2}NH, Et{sub 3}N, morpholine) to give the deprotonated complexes {l_brace}({eta}{sup 5}-C{sub 5}H{sub 3}){sub 2}(SiMe{sub 2}){sub 2}{r_brace}M{sub 2}(CO){sub 4}, the Ru complex reacts with amines by undergoing attack at a CO ligand.

Reversible displacement of polyagostic interactions in 16e [Mn(CO)(R{sub 2}PC{sub 2}H{sub 4}PR{sub 2}){sub 2}]{sup +} by H{sub 2}, N{sub 2}, and SO{sub 2}. Binding and activation of {eta}{sup 2}-H{sub 2} trans to CO is nearly invariant to changes in charge and cis ligands

Electrophilic 16e [Mn(CO)(R{sub 2}PC{sub 2}H{sub 4}PR{sub 2}){sub 2}]{sup +} complexes (R = Et, Ph) are synthesized by metathesis of MnBr-(CO)(R{sub 2}PC{sub 2}H{sub 4}PR{sub 2}){sub 2} with Na or Li salts of low-coordinating boron or gallium anions (e.g., [B{l_brace}C{sub 6}H{sub 3}(3,5-CF{sub 3}){sub 2}{r_brace}{sub 4}]{sup {minus}} or [Ga(C{sub 6}F{sub 5}){sub 4}]{sup {minus}}). They contain weal polyagostic interactions that are reversibly displaced by H{sub 2}, N{sub 2}, and SO{sub 2} (which is a surprisingly weak ligand here). The agostic and H{sub 2} complexes, as well as the gallium anions including the new species [{l_brace}Ga(C{sub 6}F{sub 5}){sub 3}{r_brace}{sub 2}({mu}-Cl)]{sup {minus}}, have been characterized bymore »« less
