Ba Sr Fe Co
BaSrCoFe crystallizes in the trigonal R3m space group. Ba(1) is bonded to one Sr(1) and three equivalent Co(1) atoms to form distorted BaSrCo3 trigonal pyramids that share  a cornercorner with one Co(1)Ba3SrFe trigonal bipyramid, corners with three equivalent Sr(1)BaFe3Co trigonal bipyramids, corners with six equivalent Ba(1)SrCo3 trigonal pyramids, and edges with three equivalent Fe(1)Sr3Co trigonal pyramids. The Ba(1)-Sr(1) bond length is 2.07 Å. All Ba(1)-Co(1) bond lengths are 3.00 Å. Sr(1) is bonded to one Ba(1), three equivalent Fe(1), and one Co(1) atom to form distorted SrBaFe3Co trigonal bipyramids that share corners with six equivalent Sr(1)BaFe3Co trigonal bipyramids,  a cornercorner with one Fe(1)Sr3Co trigonal pyramid, corners with three equivalent Ba(1)SrCo3 trigonal pyramids, and edges with three equivalent Co(1)Ba3SrFe trigonal bipyramids. All Sr(1)-Fe(1) bond lengths are 3.00 Å. The Sr(1)-Co(1) bond length is 2.07 Å.
