SrTa2Cr crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 9-coordinate geometry to one Ta(1), four equivalent Ta(2), and four equivalent Cr(1) atoms. The Sr(1)-Ta(1) bond length is 2.98 Å. There are a spread of Sr(1)-Ta(2) bond distances ranging from 2.54-3.52 Å. There are a spread of Sr(1)-Cr(1) bond distances ranging from 2.42-3.37 Å. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 1-coordinate geometry to one Sr(1) and one Cr(1) atom. The Ta(1)-Cr(1) bond length is 2.54 Å. In the second Ta site, Ta(2) is bonded in a 1-coordinate geometry to four equivalent Sr(1) atoms. Cr(1) is bonded in a 1-coordinate geometry to four equivalent Sr(1) and one Ta(1) atom.
