Kagome lattice types have been of intense interest as idealized examples of extended frustrated spin systems. Here we demonstrate how the use of neutron diffraction and inelastic neutron scattering coupled with spin wave theory calculations can be used to elucidate the complex magnetic interactions of extended spin networks. We show that the magnetic properties of the coordination polymer Mn-3(1,2,4-(O2C)(3)C6H3)(2), a highly distorted kagome lattice, have been erroneously characterized as a canted antiferromagnet in previous works. Our results demonstrate that, although the magnetic structure is ferrimagnetic, with a net magnetic moment, frustration persists in the system. We conclude by, showing that the conventions Goodenough-Kanamori rules, which are often applied to similar magnetic exchange interactions, are not relevant in this case.
