Sr Mn Mn Mn Mn Co
SrMn4Co crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Co(1) atoms. All Sr(1)-Mn(1) bond lengths are 1.32 Å. All Sr(1)-Co(1) bond lengths are 3.08 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 2-coordinate geometry to one Sr(1), one Mn(2), and two equivalent Mn(1) atoms. The Mn(1)-Mn(2) bond length is 0.63 Å. Both Mn(1)-Mn(1) bond lengths are 0.36 Å. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to three equivalent Mn(1) and one Co(1) atom. The Mn(2)-Co(1) bond length is 2.46 Å. Co(1) is bonded to three equivalent Sr(1) and one Mn(2) atom to form distorted corner-sharing CoSr3Mn trigonal pyramids.
