Scaling relations between the superconducting transition temperature Tc, the superfluid stiffness ρs and the normal state conductivity σ0(Tc) are identified within the class of molecular superconductors. These new scaling properties hold as Tc varies over two orders of magnitude for materials with differing dimensionality and contrasting molecular structure, and are dramatically different from the equivalent scaling properties observed within the family of cuprate superconductors. These scaling relations place strong constraints on theories for molecular superconductivity.
