Re4Os3 crystallizes in the triclinic P1 space group. There are four inequivalent Re sites. In the first Re site, Re(1) is bonded in a 4-coordinate geometry to one Re(2), one Re(4), and two equivalent Os(2) atoms. The Re(1)-Re(2) bond length is 1.87 Å. The Re(1)-Re(4) bond length is 1.68 Å. There is one shorter (2.79 Å) and one longer (2.94 Å) Re(1)-Os(2) bond length. In the second Re site, Re(2) is bonded in a 2-coordinate geometry to one Re(1), one Os(1), and one Os(2) atom. The Re(2)-Os(1) bond length is 2.55 Å. The Re(2)-Os(2) bond length is 3.38 Å. In the third Re site, Re(3) is bonded in a 1-coordinate geometry to one Os(1), one Os(2), and two equivalent Os(3) atoms. The Re(3)-Os(1) bond length is 1.21 Å. The Re(3)-Os(2) bond length is 2.79 Å. There is one shorter (1.41 Å) and one longer (1.83 Å) Re(3)-Os(3) bond length. In the fourth Re site, Re(4) is bonded in a 1-coordinate geometry to one Re(1), one Os(1), and one Os(2) atom. The Re(4)-Os(1) bond length is 1.82 Å. The Re(4)-Os(2) bond length is 2.95 Å. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded in a 1-coordinate geometry to one Re(2), one Re(3), one Re(4), and one Os(3) atom. The Os(1)-Os(3) bond length is 1.29 Å. In the second Os site, Os(2) is bonded in a 7-coordinate geometry to one Re(2), one Re(3), one Re(4), two equivalent Re(1), and two equivalent Os(2) atoms. Both Os(2)-Os(2) bond lengths are 2.76 Å. In the third Os site, Os(3) is bonded in a 3-coordinate geometry to two equivalent Re(3) and one Os(1) atom.
