Ge B B Ir
IrB2Ge is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrB2Ge clusters. Ir(1) is bonded in a distorted linear geometry to one B(1) and one Ge(1) atom. The Ir(1)-B(1) bond length is 0.28 Å. The Ir(1)-Ge(1) bond length is 1.37 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Ir(1) atom. In the second B site, B(2) is bonded in a single-bond geometry to one Ge(1) atom. The B(2)-Ge(1) bond length is 1.39 Å. Ge(1) is bonded in a linear geometry to one Ir(1) and one B(2) atom.
