The crystal structure described by RbHfAgTe3 crystallizes in the monoclinic P2_1/m space group. Rb(1) is bonded in a 7-coordinate geometry to two equivalent Te(2), two equivalent Te(3), and three equivalent Te(1) atoms. Hf(1) is bonded in a 6-coordinate geometry to two equivalent Ag(1), one Te(1), two equivalent Te(2), and three equivalent Te(3) atoms. Ag(1) is bonded in a 8-coordinate geometry to two equivalent Hf(1), two equivalent Ag(1), one Te(2), and three equivalent Te(1) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to three equivalent Rb(1), one Hf(1), and three equivalent Ag(1) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to two equivalent Rb(1), two equivalent Hf(1), and one Ag(1) atom. In the third Te site, Te(3) is bonded to two equivalent Rb(1) and three equivalent Hf(1) atoms to form distorted edge-sharing TeRb2Hf3 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
