The compound described by CsH3 crystallizes in the trigonal R-3c space group. Cs(1) is bonded to twelve equivalent H(1) atoms to form a mixture of edge and face-sharing CsH12 cuboctahedra. H(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent H(1) atoms. is represented by the CIF card [CIF]
