The thermal expansion behavior of isostructural variants of the colossal thermal expansion material Ag3[CoIII(CN)6] has been investigated using variable temperature X-ray and neutron powder diffraction. It was found that substitution at the octahedra... Read More about Argentophilicity-Dependent Colossal Thermal Expansion in Extended Prussian Blue Analogues..

Local structure in the colossal thermal expansion material Ag3[Co(CN)6] is studied here using a combination of neutron total scattering and reverse Monte Carlo (RMC) analysis. We show that the large thermal variations in cell dimensions occur with mi...

We show that silver(I) hexacyanocobaltate(III), Ag3[Co(CN)6], exhibits positive and negative thermal expansion an order of magnitude greater than that seen in other crystalline materials. This framework material expands along one set of directions at... Read More about Colossal Positive and Negative Thermal Expansion in the Framework Material Ag3[Co(CN)6].

Structural chemistry of (PPh4)2M(WS4)2 materials. (2008)

In this paper we discuss the structural chemistry of (PPh4)2M(WS4)2 (M = Co, Ni, Zn) materials. For M = Ni we and others have been unable to grow single crystals and we report the structure determination from powder diffraction. The material is tricl...
