The compound described by BaSm2(CoO3)2 crystallizes in the orthorhombic Pnnm space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(4), two equivalent O(5), and four equivalent O(2) atoms. Sm(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), one O(5), and three equivalent O(3) atoms. Co(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form corner-sharing CoO5 square pyramids. There are five inequivalent O sites. In the first O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ba(1), two equivalent Sm(1), and two equivalent Co(1) atoms. In the second O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Ba(1), two equivalent Sm(1), and two equivalent Co(1) atoms. In the third O site, O(1) is bonded to two equivalent Ba(1), two equivalent Sm(1), and two equivalent Co(1) atoms to form distorted OBa2Sm2Co2 octahedra that share corners with four equivalent O(2)Ba4Co2 octahedra,  an edgeedge with one O(1)Ba2Sm2Co2 octahedra, and faces with two equivalent O(2)Ba4Co2 octahedra. The corner-sharing octahedral tilt angles range from 57-67°. In the fourth O site, O(2) is bonded to four equivalent Ba(1) and two equivalent Co(1) atoms to form distorted OBa4Co2 octahedra that share corners with four equivalent O(1)Ba2Sm2Co2 octahedra, corners with four equivalent O(2)Ba4Co2 octahedra, edges with four equivalent O(2)Ba4Co2 octahedra, and faces with two equivalent O(1)Ba2Sm2Co2 octahedra. The corner-sharing octahedral tilt angles range from 8-67°. In the fifth O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Sm(1) and one Co(1) atom. is represented by the CIF card [CIF]
