Re3Pt crystallizes in the monoclinic Cm space group. There are three inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to two equivalent Re(2) and two equivalent Re(3) atoms. There is one shorter (2.28 Å) and one longer (2.61 Å) Re(1)-Re(2) bond length. There is one shorter (2.23 Å) and one longer (2.57 Å) Re(1)-Re(3) bond length. In the second Re site, Re(2) is bonded in a 10-coordinate geometry to two equivalent Re(1), six equivalent Re(2), and two equivalent Pt(1) atoms. All Re(2)-Re(2) bond lengths are 2.78 Å. There is one shorter (2.76 Å) and one longer (3.04 Å) Re(2)-Pt(1) bond length. In the third Re site, Re(3) is bonded in a 10-coordinate geometry to two equivalent Re(1), six equivalent Re(3), and two equivalent Pt(1) atoms. All Re(3)-Re(3) bond lengths are 2.78 Å. There is one shorter (2.76 Å) and one longer (3.04 Å) Re(3)-Pt(1) bond length. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Re(2), two equivalent Re(3), and six equivalent Pt(1) atoms. All Pt(1)-Pt(1) bond lengths are 2.78 Å.
