Re Ag Pb
ReAgPb is alpha boron-derived structured and crystallizes in the trigonal R3m space group. Re(1) is bonded in a hexagonal planar geometry to three equivalent Ag(1) and three equivalent Pb(1) atoms. All Re(1)-Ag(1) bond lengths are 2.69 Å. All Re(1)-Pb(1) bond lengths are 2.69 Å. Ag(1) is bonded in a 7-coordinate geometry to three equivalent Re(1) and four equivalent Pb(1) atoms. There is one shorter (2.81 Å) and three longer (2.82 Å) Ag(1)-Pb(1) bond lengths. Pb(1) is bonded to three equivalent Re(1) and four equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing PbRe3Ag4 hexagonal pyramids.
