Mn Mn Mn Mn Be Cl
BeMn4Cl crystallizes in the trigonal R3m space group. Be(1) is bonded in a 15-coordinate geometry to three equivalent Mn(2) atoms. All Be(1)-Mn(2) bond lengths are 2.85 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 3-coordinate geometry to two equivalent Mn(1), three equivalent Mn(2), and one Cl(1) atom. Both Mn(1)-Mn(1) bond lengths are 1.30 Å. There is one shorter (2.25 Å) and two longer (3.09 Å) Mn(1)-Mn(2) bond lengths. The Mn(1)-Cl(1) bond length is 2.29 Å. In the second Mn site, Mn(2) is bonded in a 15-coordinate geometry to three equivalent Be(1), nine equivalent Mn(1), and three equivalent Cl(1) atoms. All Mn(2)-Cl(1) bond lengths are 3.00 Å. Cl(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Mn(1) and three equivalent Mn(2) atoms.
