Abstract

Nb12IrAu3 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are five inequivalent Nb sites. In the first Nb site, Nb is bonded in a 6-coordinate geometry to two Nb, two equivalent Ir, and two equivalent Au atoms. There are one shorter (2.56 Å) and one longer (2.64 Å) Nb–Nb bond lengths. Both Nb–Ir bond lengths are 2.91 Å. Both Nb–Au bond lengths are 2.94 Å. In the second Nb site, Nb is bonded in a 6-coordinate geometry to two Nb and four Au atoms. The Nb–Nb bond length is 2.64 Å. All Nb–Au bond lengths are 2.93 Å. In the third Nb site, Nb is bonded in a 6-coordinate geometry to two equivalent Nb and four Au atoms. There are one shorter (2.60 Å) and one longer (2.62 Å) Nb–Nb bond lengths. There are two shorter (2.93 Å) and two longer (2.94 Å) Nb–Au bond lengths. In the fourth Nb site, Nb is bonded in a 6-coordinate geometry to two equivalent Nb, two equivalent Ir, and two equivalent Au atoms. There are one shorter (2.56 Å) and one longer (2.66 Å) Nb–Nb bond lengths. Both Nb–Ir bond lengths are 2.92 Å. Both Nb–Au bond lengths aremore »« less
