Na Sr Mn Mn
NaSrMn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaSrMn2 cluster. Na(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Mn(1) atom. The Na(1)-Sr(1) bond length is 2.25 Å. The Na(1)-Mn(1) bond length is 1.85 Å. Sr(1) is bonded in a 2-coordinate geometry to one Na(1) and one Mn(2) atom. The Sr(1)-Mn(2) bond length is 2.87 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted single-bond geometry to one Na(1) atom. In the second Mn site, Mn(2) is bonded in a 1-coordinate geometry to one Sr(1) atom.
