The structure described by AgGeBiTe3 is alpha Po-derived structured and crystallizes in the orthorhombic Imm2 space group. Ag(1) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form AgTe6 octahedra that share corners with two equivalent Ag(1)Te6 octahedra, corners with two equivalent Ge(1)Te6 octahedra, corners with two equivalent Bi(1)Te6 octahedra, edges with two equivalent Ag(1)Te6 octahedra, edges with five equivalent Ge(1)Te6 octahedra, and edges with five equivalent Bi(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 2-4°. Ge(1) is bonded to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms to form GeTe6 octahedra that share corners with two equivalent Ag(1)Te6 octahedra, corners with two equivalent Ge(1)Te6 octahedra, corners with two equivalent Bi(1)Te6 octahedra, edges with two equivalent Ge(1)Te6 octahedra, edges with five equivalent Ag(1)Te6 octahedra, and edges with five equivalent Bi(1)Te6 octahedra.

The corner-sharing octahedral tilt angles range from 1-2°. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ag(1), two equivalent Ge(1), and two equivalent Bi(1) atoms to form a mixture of edge and corner-sharing TeAg2Ge2Bi2 octahedra. The corner-sharing octahedral tilt angles are 1°. In the second Te site, Te(2) is bonded to two equivalent Ag(1), two equivalent Ge(1), and two equivalent Bi(1) atoms to form a mixture of edge and corner-sharing TeAg2Ge2Bi2 octahedra. The corner-sharing octahedral tilt angles range from 1-4°. In the third Te site, Te(3) is bonded to two equivalent Ag(1), two equivalent Ge(1), and two equivalent Bi(1) atoms to form a mixture of edge and corner-sharing TeAg2Ge2Bi2 octahedra.
