Sr Sr La Mn
Sr2LaMn crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to two equivalent Sr(2) and one La(1) atom. There is one shorter (3.21 Å) and one longer (3.45 Å) Sr(1)-Sr(2) bond length. The Sr(1)-La(1) bond length is 0.90 Å. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to two equivalent Sr(1), four equivalent Sr(2), and one Mn(1) atom. There are two shorter (3.76 Å) and two longer (4.13 Å) Sr(2)-Sr(2) bond lengths. The Sr(2)-Mn(1) bond length is 4.13 Å. La(1) is bonded in a bent 150 degrees geometry to one Sr(1) and one Mn(1) atom. The La(1)-Mn(1) bond length is 1.65 Å. Mn(1) is bonded in a single-bond geometry to one Sr(2) and one La(1) atom.
