MoCr2Pt is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MoCr2Pt clusters. Mo(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and one Pt(1) atom. Both Mo(1)-Cr(1) bond lengths are 0.63 Å. The Mo(1)-Pt(1) bond length is 0.39 Å. Cr(1) is bonded in a 3-coordinate geometry to one Mo(1), one Cr(1), and one Pt(1) atom. The Cr(1)-Cr(1) bond length is 0.39 Å. The Cr(1)-Pt(1) bond length is 0.63 Å. Pt(1) is bonded in a 3-coordinate geometry to one Mo(1) and two equivalent Cr(1) atoms.
