Sr Be Nb V
SrBeNbV crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 11-coordinate geometry to four equivalent Be(1), three equivalent Nb(1), and four equivalent V(1) atoms. There are three shorter (2.72 Å) and one longer (3.42 Å) Sr(1)-Be(1) bond length. All Sr(1)-Nb(1) bond lengths are 2.70 Å. There are three shorter (2.70 Å) and one longer (4.01 Å) Sr(1)-V(1) bond length. Be(1) is bonded in a single-bond geometry to four equivalent Sr(1) and one Nb(1) atom. The Be(1)-Nb(1) bond length is 0.59 Å. Nb(1) is bonded in a single-bond geometry to three equivalent Sr(1) and one Be(1) atom. V(1) is bonded in a distorted trigonal planar geometry to four equivalent Sr(1) atoms.
