Ni B B Ru
RuBNiB is beta oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two boron;nickel molecules and two RuB clusters. In each RuB cluster, Ru(1) is bonded in a single-bond geometry to one B(2) atom. The Ru(1)-B(2) bond length is 0.72 Å. B(2) is bonded in a single-bond geometry to one Ru(1) atom.
