Abstract

The structures of liquid and solid GeSe are studied by using neutron diffraction. The results for the solid confirm that it undergoes a phase transition from a distorted NaCl-type structure at low temperatures to a regular NaCl-type structure prior to melting. Application of the method of isotopic substitution in neutron diffraction to the liquid at 727(2) °C has allowed the coordination environment of Ge to be investigated. The results are consistent with Ge being essentially fourfold coordinated to 3 Se and 0.8(2) Ge.
