AgPb2Br5 crystallizes in the monoclinic C2/c space group. Ag(1) is bonded to two equivalent Br(3) and four equivalent Br(1) atoms to form corner-sharing AgBr6 octahedra. The corner-sharing octahedral tilt angles are 40°. Pb(1) is bonded in a 6-coordinate geometry to two equivalent Br(1), two equivalent Br(2), and two equivalent Br(3) atoms. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Pb(1) atoms. In the second Br site, Br(2) is bonded to four equivalent Pb(1) atoms to form distorted edge-sharing BrPb4 trigonal pyramids. In the third Br site, Br(3) is bonded in a 3-coordinate geometry to one Ag(1) and two equivalent Pb(1) atoms.

The corner-sharing octahedral tilt angles are 40°. Both Ag(1)-Br(3) bond lengths are 2.91 Å. There are two shorter (2.83 Å) and two longer (2.93 Å) Ag(1)-Br(1) bond lengths. Pb(1) is bonded in a 6-coordinate geometry to two equivalent Br(1), two equivalent Br(2), and two equivalent Br(3) atoms. There is one shorter (3.12 Å) and one longer (3.29 Å) Pb(1)-Br(1) bond length. There is one shorter (3.14 Å) and one longer (3.27 Å) Pb(1)-Br(2) bond length. There is one shorter (2.99 Å) and one longer (3.12 Å) Pb(1)-Br(3) bond length. There are three inequivalent Br sites.
