Cu B B Pt
PtCuB2 crystallizes in the monoclinic Cm space group. Pt(1) is bonded in a 10-coordinate geometry to four equivalent Cu(1), two equivalent B(2), and four equivalent B(1) atoms. There are a spread of Pt(1)-Cu(1) bond distances ranging from 2.34-2.43 Å. There is one shorter (2.27 Å) and one longer (2.38 Å) Pt(1)-B(2) bond length. There are a spread of Pt(1)-B(1) bond distances ranging from 2.17-2.27 Å. Cu(1) is bonded in a 1-coordinate geometry to four equivalent Pt(1), one B(1), and four equivalent B(2) atoms. The Cu(1)-B(1) bond length is 1.82 Å. There are a spread of Cu(1)-B(2) bond distances ranging from 2.41-2.50 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 5-coordinate geometry to four equivalent Pt(1) and one Cu(1) atom. In the second B site, B(2) is bonded in a distorted hexagonal planar geometry to two equivalent Pt(1) and four equivalent Cu(1) atoms.
