Ba Ba Fe Ir
Ba2FeIr crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2FeIr clusters. Ba(1) is bonded in a distorted L-shaped geometry to one Fe(1) and one Ir(1) atom. The Ba(1)-Fe(1) bond length is 1.61 Å. The Ba(1)-Ir(1) bond length is 1.61 Å. Fe(1) is bonded in a distorted L-shaped geometry to two equivalent Ba(1) atoms. Ir(1) is bonded in a distorted L-shaped geometry to two equivalent Ba(1) atoms.
