Na Re Pt Pt
NaRePt2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a distorted single-bond geometry to one Re(1), one Pt(2), and two equivalent Pt(1) atoms. The Na(1)-Re(1) bond length is 3.04 Å. The Na(1)-Pt(2) bond length is 1.03 Å. There is one shorter (1.60 Å) and one longer (2.32 Å) Na(1)-Pt(1) bond length. Re(1) is bonded in a 9-coordinate geometry to one Na(1), four equivalent Re(1), two equivalent Pt(1), and two equivalent Pt(2) atoms. There are two shorter (2.75 Å) and two longer (3.67 Å) Re(1)-Re(1) bond lengths. There is one shorter (3.17 Å) and one longer (3.38 Å) Re(1)-Pt(1) bond length. There is one shorter (3.11 Å) and one longer (3.47 Å) Re(1)-Pt(2) bond length. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 3-coordinate geometry to two equivalent Na(1), two equivalent Re(1), and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 1.35 Å. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Re(1), and one Pt(1) atom.
