Competing magnetically ordered structures in polymerized orthorhombic AC(60) are studied. A mean-field theory for the equilibrium phases is developed using an Ising model and a classical Heisenberg model to describe the competition between interchain and intrachain magnetic order in the solid. In the Ising model, the limiting commensurate one-dimensional (1D) and three-dimensional phases are separated by a commensurate three-sublattice state and by two sectors containing higher-order commensurate modulated phases. For the Heisenberg model the quasi-one-dimensional phase is never the equilibrium state; instead the 3D commensurate phases exhibit a transition to a continuum of coplanar spiral magnetic phases.
