A mechanism of negative compressibility occurring in compressed layered compounds in the presence of a pressure transmitting fluid medium is discussed within a simple model. It takes into account the excluded volume effects and soft fluid–matrix repulsion. It is demonstrated that a non-monotonic behavior of the inter-layer spacing with the applied pressure results from a competition between the applied pressure and the internal one induced by the adsorbed fluid. Recent experimental data on the graphite oxide “structure breathing” under compression in the presence of water are analyzed in the light of these theoretical results.
