The material described by YNbO2 crystallizes in the tetragonal I4_1/amd space group. Y(1) is bonded to six equivalent O(1) atoms to form edge-sharing YO6 octahedra. Nb(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Y(1) and two equivalent Nb(1) atoms to form a mixture of distorted corner and edge-sharing OY3Nb2 trigonal bipyramids. is represented by the CIF card [CIF]
