Be Re Re Ni
BeRe2Ni is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeRe2Ni clusters. Be(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Re(1) and one Ni(1) atom. Both Be(1)-Re(1) bond lengths are 0.62 Å. The Be(1)-Ni(1) bond length is 0.87 Å. Re(1) is bonded in a single-bond geometry to one Be(1) atom. Ni(1) is bonded in a single-bond geometry to one Be(1) atom.
