Using energy dispersive diffraction techniques employing synchrotron radiation we measured the effect of pressure on the lattice parameters of La2Cu04. During compression the c/a ratio remains constant up to about 150 kbar showing that the effect of pressure is isotropic, in contrast with the magnetic properties which are highly twodimensional. The results agree well with the predictions of band-structure calculations, suggesting that the bonding is governed by the La and 0 atoms and not by the Cu-02 layers.
