Anomalous thermal expansion in one-dimensional transition-metal cyanides: Behavior of the trimetallic cyanide Cu$_{1/3}$Ag$_{1/3}$Au$_{1/3}$CN

Autor: d'Ambrumenil, Stella, Zbiri, Mohamed, Hibble, Simon J., Chippindale, Ann M., Keeble, Dean S., Wright, Camille, Rees, Nicholas H.

The structural dynamics of a 1D mixed-metal cyanide, Cu$_{1/3}$Ag$_{1/3}$Au$_{1/3}$CN, with intriguing thermal properties is explored. All the current known related compounds with straight-chain structures, such as CuCN, AgCN, AuCN and M$_x$M'$_{1-x}

This study explores the relationship between phonon dynamics and negative thermal expansion (NTE) in Cu$_x$Ni$_{2-x}$(CN)$_4$. The partial replacement of nickel (II) by copper (II) in Ni(CN)$_2$ leads to a line phase, CuNi(CN)$_4$ (x = 1), and a soli

Lattice dynamics and negative thermal expansion in the framework compound ZnNi(CN)$_4$ with two-dimensional and three-dimensional local environments

Autor: d'Ambrumenil, Stella, Zbiri, Mohamed, Chippindale, Ann M., Hibble, Simon J., Marelli, Elena, Hannon, Alex C.

Publikováno v: Phys. Rev. B 99, 024309 (2019)

ZnNi(CN)$_4$ is a 3D framework material consisting of two interpenetrating PtS-type networks in which tetrahedral [ZnN$_4$] units are linked by square-planar [NiC$_4$] units. Both the parent compounds, cubic Zn(CN)$_2$ and layered Ni(CN)$_2$, are kno
