The structure described by NdBaCuO2BO3 crystallizes in the tetragonal P4bm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. Nd(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(3) atoms. Cu(1) is bonded to one O(2) and four equivalent O(3) atoms to form distorted corner-sharing CuO5 square pyramids. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Nd(1) and one B(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to four equivalent Ba(1), one Cu(1), and one B(1) atom. In the third O site, O(3) is bonded to two equivalent Ba(1), two equivalent Nd(1), and two equivalent Cu(1) atoms to form a mixture of distorted face, corner, and edge-sharing OBa2Nd2Cu2 octahedra. The corner-sharing octahedral tilt angles are 7°. is represented by the CIF file [CIF]
