The material described by YbCO4 crystallizes in the tetragonal P4_2/nmc space group. Yb(1) is bonded to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing YbO8 hexagonal bipyramids. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Yb(1) and one C(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Yb(1) atoms. In the third O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Yb(1) and one C(1) atom. is represented by the CIF card [CIF]
