Popis: The nature of magnetic super-exchange through M-O-M bonds for spin-only metal ions is nowadays fairly well understood, but for ions with first order orbital momentum, the theory is much more complicated, and the nature of the coupling between the two spin centers is harder to evaluate. I here present an experimentally determined spin density using polarized neutron diffraction in a simple water-bridged cobalt dimer [Co2(H2O)(piv)4(Hpiv)2(py)2] which is known to have a small ferromagnetic coupling between the spin centers. Visualizing the SDD could get us one step further in understanding the coupling pathways between ions with first order orbital momentum
