YReSiYReSiC crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YReSi cluster and one YReSiC cluster. In the YReSi cluster, Y(1) is bonded in a distorted linear geometry to one Re(1) and one Si(2) atom. The Y(1)-Re(1) bond length is 0.81 Å. The Y(1)-Si(2) bond length is 0.45 Å. Re(1) is bonded in a single-bond geometry to one Y(1) atom. Si(2) is bonded in a single-bond geometry to one Y(1) atom. In the YReSiC cluster, Y(2) is bonded in a distorted linear geometry to one Re(2) and one Si(1) atom. The Y(2)-Re(2) bond length is 0.81 Å. The Y(2)-Si(1) bond length is 0.45 Å. Re(2) is bonded in a water-like geometry to one Y(2) and one C(1) atom. The Re(2)-C(1) bond length is 0.71 Å. Si(1) is bonded in a single-bond geometry to one Y(2) atom. C(1) is bonded in a distorted single-bond geometry to one Re(2) atom.
