We report the magnetic diffraction pattern and spin-wave excitations in ( CD 3 ) 2 ND 2 [ Mn ( DCO 2 ) 3 ] measured using elastic and inelastic neutron scattering. The magnetic structure is shown to be a G -type antiferromagnet with moments pointing along the b axis. By comparison with simulations based on linear spin-wave theory, we have developed a model for the magnetic interactions in this multiferroic metal-organic framework material. The interactions form a three-dimensional network with antiferromagnetic nearest-neighbor interactions along three directions of J 1 = − 0.103 ( 8 ) meV, J 2 = − 0.032 ( 8 ) meV, and J 3 = − 0.035 ( 8 ) meV.
