Re Mo Ru Ru
MoReRu2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MoReRu2 clusters. Mo(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms. Both Mo(1)-Ru(1) bond lengths are 0.25 Å. Re(1) is bonded in a 2-coordinate geometry to two equivalent Ru(1) atoms. Both Re(1)-Ru(1) bond lengths are 0.52 Å. Ru(1) is bonded in a 3-coordinate geometry to one Mo(1), one Re(1), and one Ru(1) atom. The Ru(1)-Ru(1) bond length is 0.28 Å.
