Re3Os is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Re3Os clusters. There are six inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Re(1)-Os(1) bond length is 1.22 Å. In the second Re site, Re(2) is bonded in a single-bond geometry to one Os(2) atom. The Re(2)-Os(2) bond length is 1.16 Å. In the third Re site, Re(3) is bonded in a single-bond geometry to one Os(2) atom. The Re(3)-Os(2) bond length is 1.16 Å. In the fourth Re site, Re(4) is bonded in a 4-coordinate geometry to one Re(5), one Re(6), one Os(1), and one Os(2) atom. The Re(4)-Re(5) bond length is 1.88 Å. The Re(4)-Re(6) bond length is 1.88 Å. The Re(4)-Os(1) bond length is 2.39 Å. The Re(4)-Os(2) bond length is 2.20 Å. In the fifth Re site, Re(5) is bonded in a 4-coordinate geometry to one Re(4), one Re(6), one Os(1), and one Os(2) atom. The Re(5)-Re(6) bond length is 1.88 Å. The Re(5)-Os(1) bond length is 2.39 Å. The Re(5)-Os(2) bond length is 2.20 Å. In the sixth Re site, Re(6) is bonded in a 4-coordinate geometry to one Re(4), one Re(5), one Os(1), and one Os(2) atom. The Re(6)-Os(1) bond length is 1.99 Å. The Re(6)-Os(2) bond length is 2.33 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to one Re(1), one Re(4), one Re(5), and one Re(6) atom. In the second Os site, Os(2) is bonded in a distorted water-like geometry to one Re(2), one Re(3), one Re(4), one Re(5), and one Re(6) atom.
