Sr2LaCr 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 one La(1) and one Cr(1) atom. The Sr(1)-La(1) bond length is 3.56 Å. The Sr(1)-Cr(1) bond length is 0.68 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one La(1) and one Cr(1) atom. The Sr(2)-La(1) bond length is 4.76 Å. The Sr(2)-Cr(1) bond length is 1.54 Å. La(1) is bonded in a 7-coordinate geometry to one Sr(1), one Sr(2), four equivalent La(1), and one Cr(1) atom. There are two shorter (3.95 Å) and two longer (4.11 Å) La(1)-La(1) bond lengths. The La(1)-Cr(1) bond length is 3.63 Å. Cr(1) is bonded in a bent 150 degrees geometry to one Sr(1), one Sr(2), and one La(1) atom.
