Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly anisotropic Kitaev exchange interactions that stabilizes exotic ground states such as quantum spin liquids (QSL). While such novel ground state has not yet been realized, largely due to competing isotropic interactions (Heisenberg) that stabilize magnetic order and/or lattice distortions that relieve geometrical frustration, searches for Kitaev and related QSLs are still ongoing. In this context, we have recently grown the honeycomb ruthenate, Na2RuO3. Here we propose to unveil the crystal structure and magnetic ground state of Na2RuO3 by means of neutron powder diffraction. Along with our concurrent proposal submitted to MARI, we aim to pin down the nature of the magnetic interaction in Na2RuO3.
