Cr Re Re Pb
CrRe2Pb is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrRe2Pb clusters. Cr(1) is bonded in a 2-coordinate geometry to two equivalent Re(1) atoms. Both Cr(1)-Re(1) bond lengths are 1.06 Å. Re(1) is bonded in a 3-coordinate geometry to one Cr(1), one Re(1), and one Pb(1) atom. The Re(1)-Re(1) bond length is 0.38 Å. The Re(1)-Pb(1) bond length is 0.58 Å. Pb(1) is bonded in a 2-coordinate geometry to two equivalent Re(1) atoms.
