Y2Co3N4 crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Y(1), one Co(2), and two equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing NY2Co3 trigonal bipyramids. In the second N site, N(2) is bonded in a 6-coordinate geometry to three equivalent Y(1), one Co(2), and two equivalent Co(1) atoms.
