Nb2MoPt crystallizes in the monoclinic Cm space group. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 2-coordinate geometry to one Nb(2) and one Pt(1) atom. The Nb(1)-Nb(2) bond length is 1.51 Å. The Nb(1)-Pt(1) bond length is 2.89 Å. In the second Nb site, Nb(2) is bonded in a 4-coordinate geometry to one Nb(1) and three equivalent Mo(1) atoms. There is one shorter (2.29 Å) and two longer (2.89 Å) Nb(2)-Mo(1) bond lengths. Mo(1) is bonded in a 1-coordinate geometry to three equivalent Nb(2) and one Pt(1) atom. The Mo(1)-Pt(1) bond length is 0.80 Å. Pt(1) is bonded in a single-bond geometry to one Nb(1) and one Mo(1) atom.
