The material structure described by K4La6OsI14 crystallizes in the tetragonal P4/mnc space group. K(1) is bonded to two equivalent I(1) and four equivalent I(2) atoms to form distorted KI6 pentagonal pyramids that share corners with four equivalent La(2)OsI5 octahedra, corners with two equivalent K(1)I6 pentagonal pyramids, edges with four equivalent K(1)I6 pentagonal pyramids, and faces with two equivalent La(1)OsI5 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. There are two inequivalent La sites. In the first La site, La(1) is bonded to one Os(1), one I(1), and four equivalent I(2) atoms to form LaOsI5 octahedra that share  a cornercorner with one La(1)OsI5 octahedra, edges with four equivalent La(2)OsI5 octahedra, and faces with four equivalent K(1)I6 pentagonal pyramids. The corner-sharing octahedra are not tilted. In the second La site, La(2) is bonded to one Os(1), two equivalent I(2), and three equivalent I(3) atoms to form LaOsI5 octahedra that share corners with three equivalent La(2)OsI5 octahedra, corners with four equivalent K(1)I6 pentagonal pyramids, edges with two equivalent La(1)OsI5 octahedra, and edges with three equivalent La(2)OsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. Os(1) is bonded to two equivalent La(1) and four equivalent La(2) atoms to form OsLa6 octahedra that share corners with two equivalent I(1)K4La square pyramids and edges with eight equivalent I(2)K2La2 trigonal pyramids. There are three inequivalent I sites. In the first I site, I(1) is bonded to four equivalent K(1) and one La(1) atom to form IK4La square pyramids that share  a cornercorner with one Os(1)La6 octahedra, corners with four equivalent I(1)K4La square pyramids, corners with eight equivalent I(2)K2La2 trigonal pyramids, and faces with four equivalent I(2)K2La2 trigonal pyramids. The corner-sharing octahedra are not tilted. In the second I site, I(2) is bonded to two equivalent K(1), one La(1), and one La(2) atom to form IK2La2 trigonal pyramids that share corners with two equivalent I(1)K4La square pyramids, corners with six equivalent I(2)K2La2 trigonal pyramids,  an edgeedge with one Os(1)La6 octahedra, edges with two equivalent I(2)K2La2 trigonal pyramids, and  a faceface with one I(1)K4La square pyramid. In the third I site, I(3) is bonded in a T-shaped geometry to three equivalent La(2) atoms. is represented by the CIF file [CIF]
