K Pt W
KWPt crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to one W(1) and three equivalent Pt(1) atoms. The K(1)-W(1) bond length is 0.16 Å. There are a spread of K(1)-Pt(1) bond distances ranging from 2.41-4.07 Å. W(1) is bonded in a single-bond geometry to one K(1) and two equivalent Pt(1) atoms. There is one shorter (2.38 Å) and one longer (2.86 Å) W(1)-Pt(1) bond length. Pt(1) is bonded in a 7-coordinate geometry to three equivalent K(1), two equivalent W(1), and two equivalent Pt(1) atoms. Both Pt(1)-Pt(1) bond lengths are 2.92 Å.
