Be Re Re Pt
BeRe2Pt crystallizes in the monoclinic Cm space group. Be(1) is bonded in a single-bond geometry to one Re(1) and one Pt(1) atom. The Be(1)-Re(1) bond length is 2.41 Å. The Be(1)-Pt(1) bond length is 0.50 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted single-bond geometry to one Be(1) and one Re(2) atom. The Re(1)-Re(2) bond length is 2.95 Å. In the second Re site, Re(2) is bonded to one Re(1), six equivalent Re(2), and one Pt(1) atom to form a mixture of distorted edge and corner-sharing ReRe7Pt hexagonal bipyramids. All Re(2)-Re(2) bond lengths are 2.73 Å. The Re(2)-Pt(1) bond length is 2.91 Å. Pt(1) is bonded in a single-bond geometry to one Be(1) and one Re(2) atom.
