Mn Be Co Ni
BeMnCoNi crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to three equivalent Mn(1), four equivalent Co(1), and one Ni(1) atom. All Be(1)-Mn(1) bond lengths are 2.22 Å. There are three shorter (2.25 Å) and one longer (2.73 Å) Be(1)-Co(1) bond length. The Be(1)-Ni(1) bond length is 0.59 Å. Mn(1) is bonded in a 11-coordinate geometry to three equivalent Be(1), four equivalent Co(1), and four equivalent Ni(1) atoms. There are three shorter (2.22 Å) and one longer (3.33 Å) Mn(1)-Co(1) bond length. There are three shorter (2.25 Å) and one longer (2.73 Å) Mn(1)-Ni(1) bond length. Co(1) is bonded in a 11-coordinate geometry to four equivalent Be(1), four equivalent Mn(1), and three equivalent Ni(1) atoms. All Co(1)-Ni(1) bond lengths are 2.22 Å. Ni(1) is bonded in a single-bond geometry to one Be(1), four equivalent Mn(1), and three equivalent Co(1) atoms.
