Na Na Cr Co
Na2CrCo crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 1-coordinate geometry to four equivalent Cr(1) and two equivalent Co(1) atoms. There are a spread of Na(1)-Cr(1) bond distances ranging from 2.74-3.41 Å. There is one shorter (2.43 Å) and one longer (2.99 Å) Na(1)-Co(1) bond length. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to two equivalent Cr(1) and two equivalent Co(1) atoms. There is one shorter (2.51 Å) and one longer (3.05 Å) Na(2)-Cr(1) bond length. There is one shorter (2.43 Å) and one longer (2.99 Å) Na(2)-Co(1) bond length. Cr(1) is bonded in a 11-coordinate geometry to two equivalent Na(2), four equivalent Na(1), two equivalent Cr(1), and three equivalent Co(1) atoms. Both Cr(1)-Cr(1) bond lengths are 2.63 Å. There are a spread of Cr(1)-Co(1) bond distances ranging from 2.51-2.90 Å. Co(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), two equivalent Na(2), three equivalent Cr(1), and two equivalent Co(1) atoms. Both Co(1)-Co(1) bond lengths are 2.63 Å.
