Zn Tc Ni Ni
TcNi2Zn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcNi2Zn clusters. Tc(1) is bonded in a distorted water-like geometry to one Ni(1) and one Ni(2) atom. The Tc(1)-Ni(1) bond length is 1.76 Å. The Tc(1)-Ni(2) bond length is 1.76 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted water-like geometry to one Tc(1) and one Zn(1) atom. The Ni(1)-Zn(1) bond length is 2.06 Å. In the second Ni site, Ni(2) is bonded in a distorted single-bond geometry to one Tc(1) atom. Zn(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
