The material described by OsBiSe crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded in a 6-coordinate geometry to three equivalent Bi(1) and three equivalent Se(1) atoms. Bi(1) is bonded to three equivalent Os(1) and one Se(1) atom to form distorted BiOs3Se tetrahedra that share corners with four equivalent Bi(1)Os3Se tetrahedra, corners with nine equivalent Se(1)BiOs3 tetrahedra, and  an edgeedge with one Bi(1)Os3Se tetrahedra. Se(1) is bonded to three equivalent Os(1) and one Bi(1) atom to form distorted SeBiOs3 tetrahedra that share corners with four equivalent Se(1)BiOs3 tetrahedra, corners with nine equivalent Bi(1)Os3Se tetrahedra, and  an edgeedge with one Se(1)BiOs3 tetrahedra. is represented by the CIF card [CIF]
