PtAgTe4 crystallizes in the trigonal R3m space group. Pt(1) is bonded in a distorted rectangular see-saw-like geometry to one Ag(1) and three equivalent Te(1) atoms. The Pt(1)-Ag(1) bond length is 2.76 Å. All Pt(1)-Te(1) bond lengths are 2.40 Å. Ag(1) is bonded in a trigonal pyramidal geometry to one Pt(1) and three equivalent Te(1) atoms. All Ag(1)-Te(1) bond lengths are 2.95 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to one Pt(1), one Ag(1), one Te(2), and two equivalent Te(1) atoms. The Te(1)-Te(2) bond length is 1.84 Å. Both Te(1)-Te(1) bond lengths are 1.06 Å. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to three equivalent Te(1) atoms.
