Homologous critical behavior in the molecular frameworks Zn(CN)(2) and Cd(imidazolate)(2)

Abstract:

Using a combination of single-crystal and powder X-ray diffraction measurements, we study temperature- and pressure-driven structural distortions in zinc(II) cyanide (Zn(CN)₂) and cadmium(II) imidazolate (Cd(im)₂), two molecular frameworks with the anticuprite topology. Under a hydrostatic pressure of 1.52 GPa, Zn(CN)₂ undergoes a first-order displacive phase transition to an orthorhombic phase, with the corresponding atomic displacements characterized by correlated collective tilts of pairs ...
