Abstract
The crystal structure of Nd2CuO4 has been studied by neutron diffraction at pressure up to 5 Gpa. The volume compressibility value was determined as 5 .6 .10(-3)/Gpa. The decrease of positional parameter of neodymium at high p ressure has been observed. This structural change is explained by pressure induced neodymium ions charge increase.
