Pt Pt Pt W
Pt3W crystallizes in the triclinic P1 space group. W(1) is bonded in a single-bond geometry to one Pt(1), two equivalent Pt(3), and three equivalent Pt(2) atoms. The W(1)-Pt(1) bond length is 0.60 Å. There is one shorter (2.80 Å) and one longer (2.94 Å) W(1)-Pt(3) bond length. There are a spread of W(1)-Pt(2) bond distances ranging from 2.54-3.12 Å. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one W(1), one Pt(3), and two equivalent Pt(2) atoms. The Pt(1)-Pt(3) bond length is 2.19 Å. There is one shorter (2.39 Å) and one longer (2.75 Å) Pt(1)-Pt(2) bond length. In the second Pt site, Pt(2) is bonded in a 10-coordinate geometry to three equivalent W(1), two equivalent Pt(1), two equivalent Pt(2), and three equivalent Pt(3) atoms. Both Pt(2)-Pt(2) bond lengths are 2.82 Å. There are a spread of Pt(2)-Pt(3) bond distances ranging from 2.71-2.85 Å. In the third Pt site, Pt(3) is bonded in a 8-coordinate geometry to two equivalent W(1), one Pt(1), two equivalent Pt(3), and three equivalent Pt(2) atoms. Both Pt(3)-Pt(3) bond lengths are 2.82 Å.
