SrRe2Pt crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 3-coordinate geometry to one Re(1), two equivalent Re(2), and two equivalent Pt(1) atoms. The Sr(1)-Re(1) bond length is 2.01 Å. There is one shorter (1.16 Å) and one longer (1.65 Å) Sr(1)-Re(2) bond length. There is one shorter (2.90 Å) and one longer (3.29 Å) Sr(1)-Pt(1) bond length. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Pt(1) atoms. There is one shorter (2.66 Å) and one longer (2.68 Å) Re(1)-Pt(1) bond length. In the second Re site, Re(2) is bonded in a distorted linear geometry to two equivalent Sr(1) and two equivalent Pt(1) atoms. There is one shorter (2.91 Å) and one longer (3.33 Å) Re(2)-Pt(1) bond length. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Re(1), two equivalent Re(2), and two equivalent Pt(1) atoms. Both Pt(1)-Pt(1) bond lengths are 2.80 Å.
