The in‐plane collinear antiferromagnetic structure of two‐dimensional distorted triangular lattice of solid oxygen molecules is shown to have the origin in intermolecular magnetic dipole–dipole interaction. By including this dipolar interaction in the isotropic Heisenberg Hamiltonian the intermolecular exchange integrals are calculated between nearest and next‐nearest neighbours, using availale neutron scattering and X‐ray diffraction data of oxygen monolayer adsorbed on graphite. Temperature dependence of sublattice magnetization is also shown and discussed.
