Aperiodicity, structure, and dynamics in Ni(CN)(2)

Aperiodicity, structure, and dynamics in Ni(CN)(2)

By combining the results of both x-ray diffraction and neutron total-scattering experiments, we show that Ni (CN) 2 exhibits long-range structural order only in two dimensions, with no true periodicity perpendicular to its gridlike layers. Reverse Monte Carlo analysis gives an experimental distincti...

Gaia:By combining the results of both x-ray diffraction and neutron total-scattering experiments, we show that Ni (CN) 2 exhibits long-range structural order only in two dimensions, with no true periodicity perpendicular to its gridlike layers. Reverse Monte Carlo analysis gives an experimental distinction between M-C and M-N bond lengths in a homometallic cyanide framework and identifies the vibrational modes responsible for anomalous positive and negative thermal expansion in the title compound. © 2009 The American Physical Society.
