Cd Cd Si Ni
NiCd2Si crystallizes in the triclinic P1 space group. Ni(1) is bonded in a 5-coordinate geometry to two equivalent Cd(1), two equivalent Cd(2), and one Si(1) atom. There is one shorter (2.64 Å) and one longer (2.91 Å) Ni(1)-Cd(1) bond length. There is one shorter (2.64 Å) and one longer (2.91 Å) Ni(1)-Cd(2) bond length. The Ni(1)-Si(1) bond length is 2.02 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 1-coordinate geometry to two equivalent Ni(1) and two equivalent Cd(2) atoms. There is one shorter (1.89 Å) and one longer (2.52 Å) Cd(1)-Cd(2) bond length. In the second Cd site, Cd(2) is bonded in a 5-coordinate geometry to two equivalent Ni(1), two equivalent Cd(1), and one Si(1) atom. The Cd(2)-Si(1) bond length is 3.14 Å. Si(1) is bonded in a 1-coordinate geometry to one Ni(1) and one Cd(2) atom.
