RePbAs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RePbAs2 cluster. Re(1) is bonded in a single-bond geometry to one As(2) atom. The Re(1)-As(2) bond length is 0.79 Å. Pb(1) is bonded in a 1-coordinate geometry to one As(1) atom. The Pb(1)-As(1) bond length is 2.07 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted bent 120 degrees geometry to one Pb(1) and one As(2) atom. The As(1)-As(2) bond length is 1.62 Å. In the second As site, As(2) is bonded in a single-bond geometry to one Re(1) and one As(1) atom.
