Abstract: Nuclear and magnetic structures of sodium ruthenate (VI) have been studied by neutron powder diffraction in the temperature range 1.5–200 K. Na 2 RuO 4 crystallizes in the monoclinic structure, with space group P 2 1 /c. The structure consists of apical corner sharing RuO 5 trigonal bipyramids forming infinite chains running along the b axis. These infinite [ RuO 3 O 2/2 ] chains form a pseudo hexagonal close packing of rods with Ru–Ru distances of 3.51 Å within the chains and 5.30–5.47 Å between the chains. At T N =37.2 K a magnetic transition leads to an antiferromagnetic state. The Ru 6+ magnetic moments are ordered antiferromagnetically along the chains (b-axis), while the inter-chain interaction is ferromagnetic. A classical infinite chain model was fitted to the magnetic susceptibility data in order to estimate the strength of the nearest-neighbor exchange interactions along and between the chains, resulting in an intrachain coupling parameter of 2J=-86 K, and an interchain parameter J ⊥ with $\vert $ 2J ⊥ $\vert $ = 3 K.
