V Ge Bi Bi
VGeBi2 crystallizes in the trigonal R3m space group. V(1) is bonded in a 1-coordinate geometry to three equivalent Ge(1), one Bi(2), and three equivalent Bi(1) atoms. All V(1)-Ge(1) bond lengths are 2.99 Å. The V(1)-Bi(2) bond length is 2.26 Å. All V(1)-Bi(1) bond lengths are 3.39 Å. Ge(1) is bonded to three equivalent V(1), one Bi(1), and one Bi(2) atom to form corner-sharing GeV3Bi2 trigonal bipyramids. The Ge(1)-Bi(1) bond length is 2.26 Å. The Ge(1)-Bi(2) bond length is 2.26 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 7-coordinate geometry to three equivalent V(1), one Ge(1), and three equivalent Bi(2) atoms. All Bi(1)-Bi(2) bond lengths are 2.99 Å. In the second Bi site, Bi(2) is bonded in a distorted linear geometry to one V(1), one Ge(1), and three equivalent Bi(1) atoms.
