B Pt Pt W
WPt2B crystallizes in the monoclinic Cm space group. W(1) is bonded in a 5-coordinate geometry to one Pt(1) and four equivalent Pt(2) atoms. The W(1)-Pt(1) bond length is 1.87 Å. There are a spread of W(1)-Pt(2) bond distances ranging from 1.67-2.49 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to one W(1) and three equivalent B(1) atoms. There is one shorter (2.22 Å) and two longer (2.58 Å) Pt(1)-B(1) bond lengths. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to four equivalent W(1) and one B(1) atom. The Pt(2)-B(1) bond length is 2.77 Å. B(1) is bonded in a 4-coordinate geometry to one Pt(2) and three equivalent Pt(1) atoms.
