Title: Synthesis, structure and physical properties of Ru ferrites: BaMRu{sub 5}O{sub 11} (M=Li and Cu) and BaM'{sub 2}Ru{sub 4}O{sub 11} (M'=Mn, Fe and Co)

Abstract

The synthesis, structure, and physical properties of five R-type Ru ferrites with chemical formula BaMRu{sub 5}O{sub 11} (M=Li and Cu) and BaM'{sub 2}Ru{sub 4}O{sub 11} (M'=Mn, Fe and Co) are reported. All the ferrites crystallize in space group P6{sub 3} /mmc and consist of layers of edge sharing octahedra interconnected by pairs of face sharing octahedra and isolated trigonal bipyramids. For M=Li and Cu, the ferrites are paramagnetic metals with the M atoms found on the trigonal bipyramid sites exclusively. For M'=Mn, Fe and Co, the ferrites are soft ferromagnetic metals. For M'=Mn, the Mn atoms are mixed randomly with Ru atoms on different sites. The magnetic structure for BaMn{sub 2}Ru{sub 4}O{sub 11} is reported.

  • 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 » = 17.5112(4) {angstrom}, b = 11.9955(4) {angstrom}, c = 7.4684(2) {angstrom} for 2a, a = 17.5814(7) {angstrom}, b = 11.9453(5) {angstrom}, c - 7.3292(3) {angstrom} for 2b, a = 17.8642(2) {angstrom}, b = 11.9216(2) {angstrom}, c = 7.2860(2) {angstrom} for 2c, and Z = 4 for all. They crystallize as chains containing metal centers coordinated to two bridging dicyanamides, one terminal dicyanamide, one terminal chelating bpym, and one water molecule. 2a--c are the first examples of compounds containing terminal and {mu}-bound dicyanamides in the same structure. The broad maximum in the magnetic susceptibility of 1 could not be fit to any known dimer models. However, the high-temperature data were fit to the Curie-Weiss expression with g = 2.86 and {theta} = {minus}42 K. 2a--c could best be modeled as uniform 1-D chains with g = 2.04, {theta} = {minus}0.76, and J/{kappa}{sub B} = {minus}0.15 K for 2a, g = 2.34, {theta} = {minus}7.6, and J/{kappa}{sub B} = {minus}0.42 K for 2b, and g = 2.58, {theta} = {minus}5.4, and J/{kappa}{sub B} = {minus}1.42 K for 2c. Because of small exchange coupling throughout the extended networks, no long-range magnetic ordering was observed.« less
  • The new compounds Sc{sub 3}Ir{sub 5}B{sub 2} and Sc{sub 2}MIr{sub 5}B{sub 2} with M = Be, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ga, or Ge were prepared by arc-melting appropriate compressed mixtures of the elemental components in an argon atmosphere. They crystallize tetragonally with Z = 2 in the space group P4/mbm. According to powder diagrams, all compounds are isotypic. Structure determinations based on single-crystal X-ray data were performed for Sc{sub 2}SiIr{sub 5}B{sub 2}, Sc{sub 2}VIr{sub 5}B{sub 2}, and Sc{sub 2}FeIr{sub 5}B{sub 2}. Sc{sub 3}Ir{sub 5}B{sub 2} crystallizes with the Ti{sub 3}Co{sub 5}B{sub 2}-type compounds, whilemore » the quaternary compounds form an ordered substitutional variant of this structure. The M atoms are arranged in rows along [001] with M-M distances of {approximately}300 pm in the rows and {approximately}660 pm between the rows. For the compounds with M = Mn, Fe, or Co, this results in highly anisotropic magnetic properties. Susceptibility measurements with a Faraday balance in the range 7--770 K suggest ferromagnetic coupling in the rows at low temperatures. Between the rows, the coupling was antiferromagnetic for Sc{sub 2}FeIr{sub 5}B{sub 2} (T{sub N} {approx} 190 K) and ferromagnetic for Sc{sub 2}MnIr{sub 5}B{sub 2} (T{sub C} {approx} 115 K, {mu}{sub s} {approx} 1.2 {mu}{sub B}) and for Sc{sub 2}CoIr{sub 5}B{sub 2} (T{sub C} {approx} 135 K, {mu}{sub s} {approx} 1.2 {mu}{sub B}). The temperature dependence of the resistivity was measured for the compounds with M = Si, Mn, Fe, and Co.« less
