Abstract

An unusual orbital state was recently proposed to explain the magnetic and transport properties of Ba $_3$ CoRu $_2$ O $_9$ [Phys. Rev. B. {\bf 85}, 041201 (2012)]. We show that this state contradicts to the first Hund's rule and does not realize in the system under consideration because of a too small crystal-field splitting in the $t_{2g}$ shell. A strong suppression of the local magnetic moment in Ba $_3$ CoRu $_2$ O $_9$ is attributed to a strong hybridization between the Ru 4 $d$ and O 2 $p$ states.
