Cd Re Re Ni
Re2NiCd is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Re2NiCd clusters. Re(1) is bonded in a 3-coordinate geometry to one Re(1), one Ni(1), and one Cd(1) atom. The Re(1)-Re(1) bond length is 0.75 Å. The Re(1)-Ni(1) bond length is 1.01 Å. The Re(1)-Cd(1) bond length is 1.01 Å. Ni(1) is bonded in a distorted single-bond geometry to two equivalent Re(1) and one Cd(1) atom. The Ni(1)-Cd(1) bond length is 0.75 Å. Cd(1) is bonded in a 3-coordinate geometry to two equivalent Re(1) and one Ni(1) atom.
