V Ni Ni Hg
VNi2Hg crystallizes in the triclinic P1 space group. V(1) is bonded in a distorted single-bond geometry to one Ni(1), one Ni(2), and two equivalent Hg(1) atoms. The V(1)-Ni(1) bond length is 1.84 Å. The V(1)-Ni(2) bond length is 0.28 Å. There is one shorter (2.91 Å) and one longer (3.37 Å) V(1)-Hg(1) bond length. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted single-bond geometry to one V(1) and two equivalent Hg(1) atoms. There is one shorter (2.67 Å) and one longer (2.83 Å) Ni(1)-Hg(1) bond length. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one V(1) and two equivalent Hg(1) atoms. There is one shorter (2.67 Å) and one longer (2.83 Å) Ni(2)-Hg(1) bond length. Hg(1) is bonded in a 8-coordinate geometry to two equivalent V(1), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Hg(1) atoms. Both Hg(1)-Hg(1) bond lengths are 2.80 Å.
