Y Y Re Pt
Y2RePt crystallizes in the monoclinic Cm space group. Y(1) is bonded in a 2-coordinate geometry to one Re(1) and one Pt(1) atom. The Y(1)-Re(1) bond length is 2.42 Å. The Y(1)-Pt(1) bond length is 1.81 Å. Re(1) is bonded in a 4-coordinate geometry to two equivalent Y(1) and two equivalent Pt(1) atoms. There is one shorter (2.42 Å) and one longer (2.49 Å) Re(1)-Pt(1) bond length. Pt(1) is bonded in a distorted water-like geometry to two equivalent Y(1) and two equivalent Re(1) atoms.
