Here we discuss magnetic hybrid coordination frameworks in relation to the realization of new geometrically frustrated magnets. In particular, we present the nuclear and magnetic structures of one such system-the Fe2+-based oxalate fluoride framework KFe(C2O4)F-through analysis of the powder neutron diffraction and muon spectroscopy data. KFe(C2O4)F retains an orthorhombic Cmc2(1) structure upon cooling to 2 K composed of quasi-one-dimensional iron fluoride chains connected to a distorted triangular network via oxalate anions. Previous magnetometry measurements of KFe(C2O4)F indicate that it is a strongly interacting system with a Weiss constant theta approximate to -300 K that undergoes a magnetic ordering transition at T-N approximate to 20 K, yielding a frustration index, f =vertical bar theta vertical bar/T-N approximate to 15, reflective of high-spin frustration. We determine the nature of this frustrated antiferromagnetic ordering below T-N and show that the resulting magnetic structure is best described by a model in the Cmc'2(1)' magnetic space group.
