Nb Nb Mo Au
Nb2MoAu is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Nb2MoAu clusters. Nb(1) is bonded in a 2-coordinate geometry to one Mo(1) and one Au(1) atom. The Nb(1)-Mo(1) bond length is 1.07 Å. The Nb(1)-Au(1) bond length is 1.07 Å. Mo(1) is bonded in a 3-coordinate geometry to two equivalent Nb(1) and one Au(1) atom. The Mo(1)-Au(1) bond length is 1.18 Å. Au(1) is bonded in a 3-coordinate geometry to two equivalent Nb(1) and one Mo(1) atom.
